Whoa! You have had quite a day. So sorry about the hen you lost. I can totally empathize....my only buff frizzled Easter Egger died this past weekend from a prolapse. I went out in the morning and found her stiff as a board with the evidence of her condition very obvious. Thankfully the other two hens in the pen with here did not cannibalize here. That would have made it so much worse.
Broody hens can be such a handful. I had one that was broody for over two months before I finally caved in, declared her the victor, and give her some eggs to hatch. I have to admit, I learned a lot from watching her mother those chicks. She was downright impressive. Since then I've have multiple other broodies, but luckily they've been pretty easy to break since it's been so cold. I hope you have some good luck with yours. Sounds like you're more than deserving of it.
Thanks, I'm sorry about yours too. At least she went quickly, and didn't get eaten. I will pass out if I wake up to one of my chickens dead and being eaten by the others. Hopefully there will not be anymore prolapses, or any bad things, at least for a while.
I'm not sure what im supposed to do with ms. broody. I took her off the nest a few times, and she doesn't resist at all, no noises, no puffed feathers, no squirming. She will just stand where i sat her and then a few minutes later go back on the nest. I think I will tie a string to her foot and then to a brick. I will make it long so she can reach food and water but not get into the coop to sit in a nest box. I will rake the yard well so she cant build a nest either. Or she can just pretend to incubate eggs for however long she feels like. Dunno. She might stop by herself, she sure doesn't get upset when i move her, maybe she isn't really broody and is just practicing.
