Hi, I am considering hatching some eggs next year, but I need sex-linked chicks because I need to get rid of the cockerels right away so I don't get attached to them. I have a rooster that is supposed to be an Araucana, but is actually an EE (he has a tail and no beard or anything like that.) The hens I could use are Barred Rocks, RIRs, another "Araucana" (EE), and a Buff Orpington. The problem I have is the rooster. If EEs are a mix, would it be possible to get sex-linked chicks? He is reddish-orange, but two other roosters I had from the same hatchery were black/grey and grey. I think the grey was the closest of all of them to a real Araucana. I don't remember if he had a tail, and he had a big beard and ear tufts. We called him jokingly "Santa Claus." The black rooster had similar coloring to my EE hen. If three different roosters all from the same hatchery and supposedly all of the same breed had different coloring, can I trust his colors, so to speak? If the rooster isn't a problem, which hens could I breed him with to make sex-linked chicks and what would differentiate cockerels from pullets? Thanks so much.
