Hi Usha, I watched it a few times to try to pick up more clues because to me it resembles 3 possible scenarios. I couldnât quite tell, but maybe you can based on these descriptions:
Swarm practice - bees are organizing to swarm and find a new place to build a colony, leaving about half the current population and queen cells behind. This typically happens at mid morning and stops after maybe 20 minutes. This wonât continue past maybe 2 days at most - they will swarm off for real by then.
A LOT of new workers emerging and orienting all at once. Around here this happens mid-morning until early afternoon.
Robbing - bees from other colonies have targeted this one because itâs weak, and they can overwhelm the guards to raid the honey stores. If this goes unchecked it is likely to lead to the colony dying. Robbing happens when thereâs very little nectar around to forage and usually continues until the colony is completely cleaned out. Robbers come early in the morning and stay all day.
How are things now? Swarm behavior requires quick inspection and specific steps to avoid losing half your colony, or preventing more swarming if already gone. If lots of new workers have emerged then inspect at some point soonish to make sure thereâs enough room for everyone. If robbers, DONâT inspect - drape a damp beach towel or large heavy cloth over the front and sides of the hive to throw off the robbers and give the guards a chance to reorganize. Robbing screens are also helpful - you can buy or make one: check the search area for more guidance there. Let us know how itâs going!
Thank you Eva
We can rule out #3 because none of the hives are weak.
How do I differentiate between #1 or #2? Iâm inclined to suspect #2. This activity is observed around between 15:00- 16:00. Yes it last for about 15 mins I guess
I will inspect the hives tomorrow, .
My garden lizard is seen on electric poles these days. There are a few normal lizards creeping in and out, and I think it is normal. What do you say?
One of the hives is sealing off the inner lid so hard that it becomes difficult to open.
Thank you
Very glad it isnât robbers!
Sounds like emerging bees, orienting. If it were a swarm contingent, theyâd be out clustered in a tree or gone by now. So, yay! Now you can look in and decide how to provide more space - you may need to split the colony, or maybe itâs time for a super?
I like lizards! Iâm sure they enjoy your peaceful garden full of insect treats and places to hide or bask in the sun 
Cool,
I will try a super .. now is it a honey super or a space for more bees?
Which means should I put up a Queen excluder too?
I would inspect first, and assuming thereâs good nectar flow out there and your bees havenât started to prepare for swarming, sure you can put a super on! If itâs a Flow super you should use a queen excluder to prevent brood rearing in it. Traditional supers it only matters if you really want to keep the whole box free of brood, as there might be a small central arc of it otherwise.
Eva Good morning..
Looks like the swarming occured..when I observed the hive, I lost 2/3rds apparently Queen .. missing??
I observe a lot of drone cells, capped drone brood in few of the frames and quite obvious drones hovering
Quick Q.
One more hive is preparing to swarm.. this was the weak hive rescued.. and now it is loaded with brood, Queen exisits.. but the same behavior at the entrance.. hence concluding that the swarming might happen in a day or 2.
Can I swap a few brood frames from this hive to the âswarmedâ hive??
My assumptions are
Thanks ..
Catch you soon
BTW, the âsuperâ issue .. the hives seem to be very low on nectar ..but heavy 2 of them are having âgoodâ brood, and and I think âsufficientâ pollen.
So not sure if adding a âsuperâ is still needed âŚ
The âabout to swarmâ hive is kind of âheavyâ with capped brood in most of the frames.
Thank you once again!
Hey Usha! Sorry not to see your post sooner. You should split your âalmost swarmingâ hive, which will hopefully not be too late to prevent the swarm.
You have to get the queen and most of the swarm bees in it - those tend to be hanging out in the center and towards the bottom. Make sure to destroy any queen cells on frames going to the split, and leave one good looking queen cell in the parent hive. Some will say to leave more than that, in case thereâs a problem with the one you pick. Hopefully with your now-three colonies youâll end up with new brood that can be shared with anybody ending up queenless!
Iâm tagging some friends to add more advice for you - @Dawn_SD @JeffH @aussiemike 
Good Morning Eva..
I had to opt for a quick solution to create more space for the âabout to swarmâ hive.. So I took the step of âswappingâ the frames.
I could not step out of the house to get another box or super .. for 2 reasons, once it is incessantly raining hereâŚand some other personal reasons
Also, I do not have enough vacant space in my backyard to have split colonies..
Wonât adding super work??
The only other option I see is to move them out to the farm to go forward with the split.
I will be looking forward to any suggestions from the experts in the forum.
how about the problem with âno nectarâ?
Have a nice time to all of your there
After swapping I have to observe if the âabout to swarmâ hive is doing fine and Queen exists.
I will post an update in a day or 2
Thanks again
The workers that swarmed took it with them 
. Once the colony population rebounds they can make more honey.
Moving them might be best if you donât have room. Hope the rain stops soon!
It rained all night and now continues..
Iâm worried that they do not go out foraging.. But all 3 hives seem to have pollen and unsealed honey cells.
Pls advise if splitting is better than adding a âsuperâ for additional space, for the time being.
I need to drive 40 kms to purchase 3 supers/3 boxes..
Hi & thank you Eva, to address a hive that is preparing to swarm. One way to go about it if Usha wants to add another super, would be to break all the queen cells down (provided it hasnât already swarmed), place 3 or 4 of the brood frames in the center of the new super, then checkerboard the bottom box with foundationless frames. Then check every 5 days to see if the urge to swarm has passed. Usha could leave the QE out for the time being, which will make periodic inspections easier.
Sometimes the presence of checkerboarded foundationless frames can remove the urge to swarm. My thoughts are to keep removing queen cells until the urge has passed.
You could also checkerboard the brood frames in the top box.
Good Morning Jeff
Very happy to read your suggestions. I do not understand what is checkerboard..what is QE?
BTW, the âabout to swarmâ hive did not seem to have noticeable Queen cells although couple of patches of Drone cells.
I will inspect the hive tomorrow again .. again it was raining all thru here.
Have a wonderful day
Edit by Usha : QE is Queen Excluder.
Hi Usha, thank you. You have a wonderful day as well.
First of all checkerboarding is when you place empty, foundation or fully drawn frames in between existing frames of brood or honey. For example: empty frame, brood frame, empty frame, brood frame, empty frame, brood frame & so on. The QE is queen excluder.
If you were going to use a QE between the brood box & honey/extra super, I would leave it out until you sorted out the swarming issue.
If you are not finding queen cells, you could still open the brood up by removing 3 brood frames. Replace them with empty, foundation of fully drawn frames in either a checkerboard fashion, or place them on the outside after consolidating the remainder of the frames in the middle. You can place the 3 brood frames in the middle of the added super. Flank them with foundation, or fully drawn frames.
This is wonderful suggestion Jeff. Thank you. In any case you are suggesting to add extra space either as Super or remove brood.
First, I will inspect the âabout to swarmâ hive if the Queen is still living in there .. I observed the same âunusual activityâ today afternoon even after , the âswapâ exercise. While swapping I ensured that both empty frames are together and rest of them lined in their usual places, removed the feeder to create a little more space.
Now it is "Queenâs frame ", âempty frameâ, âempty frameâ, âbroodâ, âbroodâ, âbroodââŚ
So praying the Queen exists there. It did not rain today.
I have to go out to buy the super in this week.
Will I have nectar .. is it worth growing the colonies� is a question that I keep thinking.
Have a good time
Best,
Yay Yay..Eva, Jeff, good news.
I got a empty hive with 4 frames and a feeder.The best part is I had to go only 3kms to meet a lady who is into training on Bee Keeping.. she seems to have 3-4 species being matained,
@Jeff, I checked the âabout to swarmâ hive today with the help of another expert. The queen exists. So I shuffled the frames as Jeff with 2 empty frames at the centre.
This expert opened the âswarmedâ hive and as soon as he opened the inner lid, he says, the queen should exist here too.
We will inspect the hives again 2-3 days later and update.
Thank you for the suggestions.
Best,
Fantastic news all around, Usha!
Good morning Usha, youâre welcome 
I agree with @Eva Did the expert look for proof of a queen? Thatâs all I do. As soon as I see sealed worker brood, I close the hive up again, on account that young queens can be prone to âballingâ by the colony during inspections. Itâs also important to know the timelines of when the colony swarmed, so that you donât look in too soon.
Cheers
