Has anyone ever seen something like this before? I just saw it for the first time on one our chickens this morning. Other chickens don't appear to have anything similar, but we're going to do a more thorough inspection this afternoon. She's acting normal. Eating and drinking fine. She's a little over a year old. We have around 25 chickens, so there's no telling how long she's looked like that and we just may not have noticed it sooner. It's hard to tell in the picture because it's a little blurry, but the left side of that lump is whitish-light bluish in color. Thanks!
