A fox managed to get in to my hen house. It killed 2 young pullets, one is missing, so assume he took that one away with him. One other pullet was on the coop floor, and I thought she was dead, but she is indoors now and still alive. I have checked her over but can't find any injuries. She is laying on her side not moving at all. Have tried giving her electrolytes and scrambled eggs but she would not even attempt to try drink or food. Could she just be in shock? Another hen seems to be limping and her toes are curled under her foot, what can I do for her?
