I have a rooster that is limping and I cannot find why. There is no signs of injury, wounds, scrapes,cuts, bites, bumblefoot, scaly leg, no missing nails or toes. There is no swelling either. He eats and drinks but limps so he does sit down often while his hen forages nearby. He cannot jump high or get down. If he's on my porch he has a hard time going down the one step I have. I suspect a sprain or something. Could I give him baby aspirin? If so for how long and often? He's about 7 pounds give or take and I'm unsure of his age because I adopted him. He is not mating yet or crowing but he is identifiable as a rooster so my guess is around 5 to 6 months old. In the image from left to right he is the first one. The second is his hen they are a pair.
