I don't actually know if he's mute but it seems like it. Hes 8 months old and I'm pretty sure he has no interest in crowing. I took him and his 6 hens in when a lady nearby couldn't keep them. I had my own group of very bossy seniors already but I felt bad for the lady. There are 2 silkies and 4 bantams. What does he look like?( Besides handsome ) and why won't he crow for me!?!
