I stupidly let my dogs stay out while putting the chickens in for the night. They had been good about leaving them alone, and thinking this was a peaceable kingdom, let down my guard. One dog went after a chicken and bit it's back about 3 inches from its tail. The gash is L shaped, the organs can be seen if the skin flaps back. The rooster then jumped on the chicken to apparently try to get it in the coop, but I was afraid he would hurt her even more. So have her in a little bed of her own with food and water. What else can I do? She has one leg that seems off, but wings seem to function. I am so sorry I didn't protect her better.
