I have a 4 yr old Bantum Rooster. About 4 weeks ago we noticed he was not walking. He would take 3 steps then sit down. He his eating and drinking. I have tried salt baths, he has been wormed and given Nitri-Drench, supertonic, banixx and rooster booster spray on his legs. Nothing seems to be working. Please help if you can. Also took him to the vet who prescribed pain meds.
