Gobbler can't walk. Plz help

One of my royal palm tons is having a very hard time walking. His legs are red kinda like they have fever in them. When he does walk he has to use his wings for balance. I lost about 5 poults when they were 8 weeks to cocci I think. Could this be cause from this? My other Tom walks just fine but don't want him to cath what ever it I and get like this.
