Hello all. New to raising chickens and loving it! I was given 4 blue Cochin chicks in early November so they would be about 4-5 months old now I would say. My rooster grew up very fast and he is a big boy. A few days ago, I noticed him limping on his right leg and when he would step with it, he would put it down several times before actually moving forward on it. He is now not walking on it at all and it sticks straight out in front of him, even if i adjust it and put it back up under him. I don't have a perch in the coop so there isn't anything he could have jumped off or fallen off to injure himself, and he is with 2 hens and 1 other rooster (we thought he was a hen too until a few weeks ago). I'm worried about him suffering of course, but he doesn't act like anything hurts if I'm prodding and poking around and i can't feel any obvious breaks or bulges if I'm running my fingers all over the leg. There aren't any sores or scabs on the foot and it doesn't appear to be swollen or anything. He has feathered legs though so i might be missing something. He also doesn't grip your finger with his toes if you push into the middle of his foot like he does on the left side. He eats and drinks well, it just makes me sad to watch him flop and flap over to the dishes. I don't want to completely pull him from the coop b/c i pulled a hen a few weeks ago and they picked at her relentlessly when i put her back. He isn't being picked on and his hens lay with him and the other rooster steers pretty clear too. I was told to try polyvisol and selenium which i got, but I'm not sure how much to give for how long or if this will even help whatever is going on with him. Any advice is welcome and appreciated and I hope I'm providing enough info to flip a light on in someones head to an answer. Thank you in advance.
