I have been reading about Black and red Sexlinks and would like to try and incubate some next week. I understand that a red roo and a Barred Rock hen would make a Black Sexlink- is that correct? I have a Comet roo and some Barred rocks, would that work? Or did I reverse that combination? The roos I have are: Australorp Red (?) Comet Barred Rock BO The hens I have are: BR Comets Delawares RIR BO Is any of those combinations useful? Thank you all for your help.
