1st I had all my hens with 2 cockerels then I split the girls into 2 flocks .Now I have one rooster with all the hens and keep one as a spare lol Glad I don't have more than one in the flock now(19)
Bake as many delicious meals as you can that require eggs so he'll learn to associate the eggs with good food . Don't mention you're using the eggs or he'll refuse to eat it. Its a psychological issue he has to work out in his own mind.Give him some time.
Maybe you can talk hubby into building a coop just for the guys? You might actually like a hen only flock better. Mine are friendlier when they don't have a rooster
