Wondering if anyone has seen this type of thing before and whether it's something to worry about. This afternoon, when my broody hen ruffled up her feathers I noticed this growth on her skin. It's round and pink, firm to the touch, and about the diameter of a dime/size of a marble. It doesn't seem to hurt her at all when I touch it. I don't see anything else like it anywhere else on her body.
The picture is not very good. I will try to get a better one tonight when I'll have an extra set of hands and am not trying to take a picture while parting feathers and holding a hen!
