New to BYC-Florence is one of our older hens. Got her at an unknown age from a free range farm with goats, dogs, and lots of other chickens. She is a bantam seabright. She is our best layer, and today she was laying/sitting on her side. She looked odd so went to go to her and she twitched her head in a semi-circle (and kept doing this periodically). She tried to get away and couldn't stand or walk. I thought it might be her feet, so I brought her inside and washed her feet. There was nothing that I could see that would tell me what was wrong. She can't fly (even a little bit) and will instead, fall to the ground, hard. Don't worry, I didn't let her go, she got away from me and fell from my arms by accident. I can't afford to take her to the vet but I have two other hens that I'm concerned about. Should I isolate her from the other chickens? I don't want her to struggle and I'm concerned about her being able to get around to eat and drink. Should I bring her inside in an aquarium to keep her safe and away from the others? ANY suggestions are welcome. I am a wreck and so is my sweet Flo. Please help. Thank you.
