One of my Salmon Faverolles is acting very strangely.. She spent all day in a nesting box, and has not laid an egg. Everybody else has been in, laid, and back out but she just stayed. At one point, when the other Faverolle persisted in looking in on her she kind of freaked out and popped out of the box all ruffled feathers and clucking. She left the coop and went out into the yard but stayed ruffled up. She kept on clucking repeatedly and kind of scratched around in the dirt, but, would alternate between that and picking at her feathers near her tail. Then she started picking fights with the other chickens who weren't doing anything. She dropped her wings and acted like a rooster a few times, too, growling at one of the other hens. We don't have a rooster, and she is only eight months old. She has been laying for a few months now, smallish eggs, because she is a new egg layer. She kept going back into her nesting box, and I would leave her be except to bring her out to have something to eat and get some water in her, which she did on her own really well, so, her appetite isn't off. It's her behavior. If I hadn't brought her out, she would have stayed in that box all day with no food or water. She had a small bowel movement so she is passing something, but, I know that doesn't eliminate the possibility that she has an egg stuck in there. She freaks out when I carry her. She has never liked to be held, but, she hasn't freaked out before, just complained. I feed my hens layer crumbles, and have oyster shell available for them, but, yesterday we cleaned out the coop and the oyster shell got a little lost in the process, so, she hasn't had any of that for about 24 hours. I dont know how much layer feed she eats, but, when she was out she had a little bit on her own. She had some black oil sunflower seeds and scratch grains, and the oyster shell was there so hopefully some of that, too. I also whitewashed some of the coop yesterday, and I can still smell the lime a bit inside. So, that worries me. I've never whitewashed before, so, I followed the advice on this and several other boards in how to do it,but, it still makes me worry.
