My Splash Orpington has stopped eating in the past 2 days. She hurt her leg somehow and was limping so I separated her and put her in a small cage to heal. She seemed to be doing okay at first but after 5 days she barely eats at all. She lies on her side most of the day off her leg and will not touch food or water.She is only 3 months old, still a youngster. Should I be concerned? Is this normal when a chick is in pain?
