I have a polish cockerel, 15 weeks old. Although he very much looks like a roo - pointed crest, saddle and hackle feathers - he's a sissy. Scared of his own shadow. Every rooster I've had before him was mature enough to crow and try to mate by 15 weeks. Are polish just slow to mature? I'm going to keep a rooster out of the next hatch because I am starting to think that the polish might not be a very good flock protector.
