I am a new beekeeper, as of May. I started with a 5 frame (medium) nuc from a reputable beekeeper in our area. The bees seem to be growing well and drawing out comb at a good rate, despite having never been fed. I do, however have some concerns about them that seemed well founded at my last inspection. I will try to post more details later but wanted to start with these pictures from this past Thursday and get the opinion of more experienced beeks. How concerning is it to have some mishapen larva? I’m worried about EFB but surely there are other causes as well?
