I mated my awesome BO roo to my very dark red RIR hen and plan to remate one of the red son's back to the dark RIR hen next but in the meantime, I am raising four pullets and another young roo from this mating. Do you find these birds are as hardy as the purebred BO or RIR? Do you find these birds good egg layers or good eating? I am finding they are sweet birds but possibly not as hardy as the purebred parents. My plan is that I want more RIR but am trying to get the broodiness back to raise more so will breed the red son back to his RIR mom hen this Spring for a deeper color than the first mating produced and try to get that broodiness back so I won't have to incubate. Is it worth it? I'll have to go out and get pics in a few minutes of the first offspring. I could just put RIR eggs under a BO hen, instead... what are yours like? Has anyone else had results to share from trying this same thing?
