I currently have a black Cooper rooster and some hens. I am thing to add some more hens, so I can have different color eggs. Also if I hatch some chickens, I can still get different color eggs from the second generation. I am thinking to only keep one rooster. If I add some Easter egger and brown egger hens, should I still use my black Cooper rooster for breeding? I am just afraid the off spring will not be good egg layer, as Marans are not very good in laying. If there is other better choice of rooster breed, which breed I should choose?
