Hi All, I have a small flock of mixed variety of multipurpose hens and 1 rooster. Recently one of my 2 yr old hens ( a production red) started having a weird spasm that shook her head from side to side. She started avoiding the others when the twitching started, they've been cooped during winter but have ample space to walk around. This morning I went out like I always do to feed and check on them and she was sitting on the floor, head still twitching and didn't try to get up when I approached or when I filled the feed stand. So I picked her up and put her into a pen in the other side of their shed (shed is 2 rooms) with her own food and water as well as some fruit I know they enjoy. When I got home from school several hours later, she had manuvered herself to the water but was otherwise just laying in the pen with her wings somewhat splayed on her sides. She has no eye/nose or butt discharges but she does not look well and I'm pretty sure she will not last the nite. I plan to take her to my vet in the morning as I need to know what this is so I can protect my other chickens and we eat their eggs. There is no way they have been exposed to any other birds. These chickens are super spoiled getting warm oatmeal mixed w/ feed on cold winter mornings, fresh fruit and veggies several times a week and I am feeding them the same feed they have always gotten, a mix of poultry layer crumble and scratch grains. I haven't let them outside yet because I seeded their yards so it would be nice n green for them in a couple of weeks. They are not in cages or cramped quarters Please advise!
