I just got a 2 month old silkie/polish mix yesterday. She is eating and drinking fine and her poop looks normal but she hardly ever walks around. She will lie down next to the food and water and eat and drink without getting up. She was outside when I bought her but I am fixing up my coop so I put the chickens in tubs temporarily. When I take her out of the tub and put her down on the floor she will lie down on the spot. She looks healthy. I was thinking she might be tired because she didnt get sleep with the amount of chickens in her old coop. I heard of a disease where the chicken will close its eyes and hang its head then pop up again. She does that occationally but she is actually falling asleep when she does that I think. Any ideas? Is she sick? Here is a pic of her.
