I am writing from outside Boston, MA USA. The weather has been spectacular.
I installed my flow frames about 10 days ago. I painted them with some wax from the hives and some purchased. Around the same the same time I ended up removing two frames of brood (one looked to have queen cells and got the advice from this forum to remove) and a frame of honey and put them into a nuc and put in three new frames with wax foundation in the top brood box.
The hive is very robust. Bottom box has lots of brood and nice patterns. Top box has 3 frames of capped honey. The three new frames all have drawn comb and some nectar.
I see bees crawling on the flow frames but do not see any evidence that they are deposing any nectar. Can someone give me a general idea of how long it takes the bees to prep the flow frames and what I should be looking for to know that they are doing that.
