I have a rooster that is about a year old or more. He started showing signs of difficulty walking. I monitored him for several days wondering if he tore a muscle and might start improving. Instead, it got worse and now he can not walk or stand on his own. This all happened around the time that a neighbor gave us some chicken feed, which is why I think it could have been a vitamin deficiency. I started adding roosters booster to his feed daily for a week, then we had a coccidiosis outbreak in the flock and I had to stop the vitamin treatment. It has now been about two weeks that he has been receiving 3 ml of Rooster Booster Poultry Cell liquid daily, and scrambled eggs with 400 IU vitamin E capsule squeezed onto the eggs, plus good quality chicken feed. His poo is normal, he eats and drinks like normal. Comb color is bright red like always. I am not seeing any other issues besides not being able to walk. When I pick him up, he will kick his legs, but he just can’t hold himself up. He is a big boy. My questions are…should I be doing anything different to help? At what point do I call it quits?
