Hi there some advice please. I have lots of different OEG Bantams all seperated, but just purchased 1 Black OEG rooster and 4 hens, they are grown but still tiny. My coop will be divide half for my Buff Orpingtons and the other half will have seperate pens for my bantams all with there own runs as well as a large run for B. O. I just put my Black OEG in with the Buffs, I am very particular about not mixing, will the Buff roosters breed the Black OEG or vice versa? To see the size difference I dont see how its possible. Thanks, Eric.
