Okay I have a group of hens and roos that are 15 weeks old this Tuesday. So far I haven't seen any squatting and I haven't seen any mating with the roos. The hens are getting redder combs but so far no action. Lately I am hearing one of the roosters doing the bok bok bok bakock egg song like a hen would do after laying an egg. Is this normal? Do the roosters teach the hens the egg song before they start laying? Just wondering. They are sex linked so there is no way to get the roos and hens mixed up. Hens are all dark reddish color and the roos are white both with large red combs and wattles.
