Hello! This is one of my 2.5 month old roosters. Today, I noticed that he has a bit of an underbeak. I am not sure if he's always had it, tried to look back at pictures to see but he has two identical brothers and I can't really tell (his brothers' beaks look fine). It doesn't seem to be preventing him from eating and drinking, and he is the same size as his brothers. I'm also currently trying to find him a new home and thinking this may not be a good selling point for him as it's probably not a good thing for mating right? Can it get progressively worse? Should I try to correct it, and how? Thanks for your advice!
