I got two hives given to me and am in the process of cleaning them out. Most of the hive seems fine, but two of the frames have something that looks like bits of wool in the middle part of the comb. It doesn't look like it's mould or fungus or even anything like insects. Is it possible that it's something the bees carried into and accidentally incorporated into the comb or is it actually a disease or something I haven't read about yet. (Which is very likely, since I'm just starting)
