Just be patient. Some cockerels don't crow or mate until they are 6-8 months old, although some do start younger than 3 months. There is a wide range of normal.I was curious if anyone can help me answer this as well so he’s now 3 months but he doesn’t crow at all! He’ll make a few small noises in the morning but after that no sound and he’s still learning to get along with the hens ( some refuse to be near him still and most still won’t squat for him) so how can I teach my girls to accept a roo
As he gets older and more mature, he will most likely learn to crow properly, and the hens will almost certainly start to respect him and accept his advances as time goes on. He's still quite young and immature, and the hens are (rightly) not impressed yet.
