I have a 24 week old rooster, he hasn't started crowing or mating and is a little scared of the girls. He is a light Sussex and is bigger than all the hens and doesn't defend his territory either like the other roosters I've had in the past. Will he ever start? Would putting him a seperate cage for a couple of weeks help to change the pecking order? The 3 older hens used to attack him when he was about 15weeks old so could this have something to do with it?
