We have an approx. 7 month old silkie bantam hen whom I am very worried about. She won't leave the nesting box and has been in it all day. Twice we did get her out, she walked fine, are food and went out in the run. Each time, when we went back to check in her, she was back in the nesting box. I have her via a syringe water with electrolytes twice but don't know what else to do!!!!
