My Silkie has been broody for a few days. She sits in the nesting box on the golf balls we put there all day. This morning she was nose down in the nest and making a weird trilling noise. (I should mention that the other girls had been scraping all of the hay out of the nesting boxes so I stopped putting any in there and my Silkie started plucking her tummy feathers to soften it, and now she is bald underneath.) Anyway, the golf balls are under her chest instead of her tummy, so I am hoping this is normal and she is not sick. Any suggestions? She has no discharge from eyes, nose, or mouth. I see no lesions on her anywhere either.
