I have a 32 week old silkie that has never crowed or later. I assume she is female, she is very small. I have wondered why she hasn't layedone yet, but now when I went out earlier, she is moving like she's drunk. Not running from me like normal. I saw her later drinking and so I'm sure she's eating. Everyone else seems fine. My husband went to check on her tonite and she was laying in the nesting box. He went to help her up to the roost and she threw up on him. I am assuming she is sick, but wondered if they can have issues laying and have these symptoms?
