She's not loosing feathers, broodys will pluck out their own feathers, to make better contact with the eggs. Have you read this thread at all? Put the hen in a raised, wire bottom cage, with water and food, for four full days. Do NOT let her out, until those four days have passed. You can let her back with the rest of the flock, after she gets past the broodiness. I have a couple of BOs. that sometimes it seems one or the other is broody, every other week. If they are not going to sit on fertilized eggs, they need to be broke. IMO, it's cruel to have them potentially sit for weeks, maybe months, for nothing.
Yes I have read this, but only skimmed through. Thanks for these methods, I will try them. We didn't know she was broody for a while, and I totally forgot about threads, I wish I could have asked sooner
