hey all! I have a brown leghorn that for some reason has always picked out her own chest feathers. She’s not even a year old, and lays great eggs for us.she doesn’t exhibit other brooding behavior like trying to sit on her eggs all the time so we’ve just let her be. The brood patch never seems to bother her and it never seems horrible. But now it has developed a lump under it. I suspect it may be that she picked too much and it got infected but not sure how to verify that or how to treat it. I’m not in favor of taking our chickens to the vet but also don’t want her to die a very painful death. Anyone have any thoughts? She’s a bit wild so couldn’t get closer pictures but hopefully you can see how big the lump is. Thanks for the help!
