What's going on here?

These bees are from a removal I did a few weeks ago. The bees are doing really well,  been rebuilding and making comb like crazy. I have had to give them more room twice already. Today I went into them and found this. This is a piece of old comb that was in the original hive (chicken house door)  with them. This is also the only piece of come like this. They seem to be chewing the brood out of it. The rest of the frames are fine. Lots of bees and lots of brood in all stages. What's goin on with this one?

It could bee the frame was placed too close to another fat frame or they were diseased by something. If it is only a few cells they are doing this to, I would not worry about it.
There is a better chance the flow has stopped and there is a shortage of food so they are cutting back on the amount of food they are feeding. I was teaching at the Honey Bee Festival in Jacksonxille yesterday and a single frame observation hive was pulling out larvae and moving them all around the frame trying to get out of the hive. They had no food coming in and in one day they were stressed enough to start reducing the open larvae population.

Fish, what Jim said, plus maybe brood chill as this was part of the original removed comb.  Either way, only a small patch and rest of the hive is thriving.

So, lack of stores, as Jim text
Brood chill
Brood over heat
Only a small patch of brood is affected so I would rule out Disease or varroa.

Again, great close up pic.  Only a few cells in the pic but I see no varroa frass.

I had to crop this pic down to size to post here. It is only this one frame, but there is quite a bit of it. Only this one frame though.  I did stop feeding all of a sudden. Would that do it?

[BeeMaster2]

Yes, if there was no other food coming in.

Thanks jim. Theres tons of pollen coming in but I dont think much nectar at all right now. When I put out sugar water they get on it like it's the only thing available.  Because it probably is.
