My young cockerel (Olive Egger) has been dog attacked. Looks fine overall. Minor cuts and bruises, some broken shafts. But he won't move his left leg too much. Felt his hips, joints and feet. Don't feel any breaks, leg is kind of loose. He is favouring his left, and lying down more on his left side. Not lying down a normal chicken way if that makes sense. He will grasp a little with his feet when touched. He's in shock, I think. Have him resting in our "patient" box in our house. Dark, quiet and cool. Gave him water with Vitamin B complex and electrolytes and some chick grower mash (his normal food). Not sure what else to do for him. Would like to treat him at home, we are very rural and there are no vets around that deal with birds or farm animal sickness/injury. Hoping that we can help him recover. Worried about him. Thanks in advance!!
