Hi. I have a six-month-old female Australorp who seems to have some neurological problems. A couple of weeks ago, I started finding her outside the coop at night when I would go to shut the door, presumably because she was having trouble getting up the ramp. Some nights she makes it in on her own, but most I have to put her there. I also have to take her out in the a.m., since it is hard for her to come out on her own and she falls. She walks normally (but not as quickly as the others), eats, drinks and poops normally. She doesn't seem to be able to use her wings at all to stabilize herself. She doesn't attempt to get away when I pick her up and she falls asleep randomly during the day. Because I had two chickens die this fall (one was paralyzed), I feared it must be Marek's. I'm a new chicken owner, so I didn't know I should get vaccinated chicks. Anyway, it's been a couple of weeks and she's not getting better, but she's not getting worse either. Might she be this way forever? I put Corid in their water for five days and directly dosed her with Safeguard, in case she had coccidiosis or worms, but there was no change. I also dusted her with viper insect dust in case of mites or lice. Some days she and one of the other two chickens seem to scratch a lot, but I can find no evidence of parasites on any chickens or in the coop. Any insights?
