Help! One of my girls suddenly has major feather loss. It looks plucked?! I haven't given her a thorough check in the last 3 days, but this stood out to me immediately upon seeing her this afternoon and looks very recent. (I didn't notice it yesterday when I let them out) Any ideas what it could be? I have 3 Buff Orps, all just over 6 months old. Plenty of room in their coop and run, and they free range a good portion of the day. Their coop is rather clean generally speaking and I can't seem to see any mites, etc. Any ideas what it could be? It's worst on her lower stomach area, and some on her thighs. I have seen a few posts talking about giardia. Could it be there? I feel badly for her! Thanks in advance for any help!
