I just noticed today when I let my 1 year old rooster Kernal out that he is limping. He's is his normal self but just limps when he walks or hops when he runs. Nothing else is wrong with him. I'm hoping he just spranged something from jumping off his 7ft tall perch outback yesterday. I looked at his legs and nothing seems to be hurting him or swollen. Can I give him some asprin to help him? and how much would I give him? Please help this is my baby boy.
