Having just had my fears confirmed that my two RIR pullets are, in fact, Production Red cockerels, I'm wondering what kinds of hens, other than Barred Rocks, will make sex link chicks with my boys. I already have 2 BR's and will now need to get at least 2 more hens in order to replace the pullets that turned out to be cockerels. I certainly love my BR's, so I could just get more of those. But I'm interested to know what other sorts of chickens might work. Buff O's? We do have hawks around, so I'd like to avoid any pure white hens.
