Hi everyone, forgive the length of this story. We have a 3 year old Americauna who a few weeks ago woke us up during the night squawking and I found her laying on the ground in the coop. There was nothing obviously wrong with her, no sign of injury, but she couldn’t walk. I soothed her and she calmed down and I put her back in the coop. That morning, she flopped/hobbled out with the others and ate some scratch. I also hand-fed her some food and water. It was Christmas morning, we couldn’t take her to the vet, and we were on our way out of town for a couple days. We did not have anyone planning to come check on the chickens because we have a solar door and it was only for a couple days. There was nothing we could do so I put her in the coop and left her in a crate in the coop with food and water and hoped for the best. We had a security camera in the backyard, but there was no sign of her the whole time we were gone. I came home 2 nights later expecting to find a dead chicken in the coop, but there she was up on the roost sleeping with the other chickens! The next morning she came out with them as if nothing ever happened. Maybe she had injured her foot and just fell off the roost that night, I thought. For the next few weeks everything seemed normal. But then 3 days ago, the exact same thing happened again. Woke us up, laying on the ground in the coop crying, couldn’t walk. I watched her closely for the next couple days (she still had an appetite and I couldn’t see any sign of injury) and sure enough, on the 3rd day, she was able to stand and started walking again. Tonight she is back up on the roost like nothing happened. I have no idea what is going on! I wondered if she was egg-bound but she actually laid an egg on Day 1 of the latest episode. Also I suspected Marek’s (paralysis) but I contacted the feed store where we got her and they said they have always vaccinated their chicks. I also read about vitamin B deficiency so I was feeding her Brewer's yeast as well as giving water with apple cider vinegar, maybe this helped? Has anyone ever experienced anything like this???
