I may be looking too. I have a Golden Comet and she is a sweet bird. I get the impression when I let them out that she is "acting" like she is trying to sneak by but will walk slow enough that I might pick her up. If I do pick up a different chicken she will stop and look at me like "Why did you pick up her instead of me?"
I do think Katy was right on with the Mereks. My chickens not favoring any one leg, both legs are very weak. I have to hold her up for her to eat/drink. She can't stay balanced. This morning she was leaning against the side of the box (in my garage)with both feet out to her side. She looks like she is melting.. just spreading out like a big, feathery pancake with a neck and head on top.
I think next time I purchase chickens will be vaccinated chicks. It is heartbreaking to see her struggle but I have read the paralysis can be transient and clear up after a few days. So I am doing what I can and hoping it is in her best interest. I fear my other americana is at risk. The gold comet is older and laying so she may have immunity.
