I believe my ignorance has offended everyone on the genetics/breeding area so would someone here with knowledge PLEASE humor me. I want a black jersey giant but have limited space now and bjg would be the roo. if a 13 lb bjg were to mate with my 6-8 lb hens SHOULD they be OK? I would think the answer is definitly "yes" but given everything else I have been wrong about I am just trying to be sure. am going to get more layers and son wants a black jersey giant and I want other breeds of hens so we have decided (since we want a roo for possible raising of our own layers) that the roo could be the black jersey giant he wants but I cannot do it if he more than likely will break my hens(not to mention what their eggs would be like) thanks
