I'm thinking this began some yesterday but we were not home enough to really pick up on the signs of her slowing down. Today, lights are on but nobody is home. Barely moves. Standing like she's almost sleeping (very "square"), stomach feels hard & bloated, her cloaca (sp?) area is very dirty and her breathing is labored. We isolated her just now to a quiet dog crate on our porch because one of the other hens just tried to take her out with pulling on the comb and then kicking with feet. So, they notice something is wrong too. She hasn't laid but 3 eggs since molting in September. Nothing recently. I did start the girls under lights about a month ago. The others are laying regularly again. I have given her some colloidal silver on a piece of bread, so she is eating; albeit, slow and uncoordinated. We think she'll probably pass soon. Any ideas or advice?
