Today to my dismay as I came home from work...I found one of my birds being pecked at! Almost his entire leg is an open wound! His wing is badly injured also. Im wondering if it is because they are missing something in their diet? Any suggestions!!??! I moved my injured guy out of the pen and placed him in isolation...I am not sure which one initially hurt him but I am concerned for my other chickens. Buffcochin, 12 weeks.
