I have a 7 month old Silkie cockerel who still doesn't crow, and I know for sure he is a cockerel. He is very submissive and we have another dominant rooster that lives with him that crows often. He is at the bottom of the pecking order, and is one of the sweetest birds in our flock. I want to use him in my breeding program in the spring, so I was wondering why he is still showing no signs of crowing or mating? Is this common in Silkie roosters? Thank you and happy new year everyone!
