My buff has been brooding for almost 3 weeks. We’ve blocked access to boxes but she just finds another place, even on the ground. We take her out several times a day. We blocked access to her coop for several hours but the second we open it, she’s back at it. She’s getting skinny so I’m concerned. I’ve been advised to put eggs under her then get a couple of live chicks and swap them out. Should I do that? Any other suggestions?
