I have three Buff Orpington hens to produce meat birds with and was given a Rhode Island Red rooster. So I have let him have the run of the yard. I have hatched out several eggs from the Orpingtons and luckily most are hens. But I have a 1/2 and 1/2 Rooster now maturing. He is bigger than my RIR roo. Is there any concern (genetically speaking) with letting my new 1/2 and 1/2 be the one to fertilize the Orpington eggs so I will get a better, closer to pure Orpington meat bird?
