What rooster will you be using? Are you going for black sex links or red sex links? The Delaware has both silver and barring so both options are open to you. The pullets from that cross (Delaware rooster over a red sex link) will have both of those sex linked genes.
One requirement for sex linked chicks is that you have to be able to see the difference in the red/yellow down for red sex links or the spot for black sex links. Since the hen will be a mix you could possibly get different down patterns on the chicks when you try to make the sex links so there could be some challenges, but either could easily work.
I was going to breed my Delaware rooster to a couple RIR hens and I was thinking I'll add in a few more red sex linked hens to produce silver parent stock, mainly pullets to breed with my RIR rooster and produce red sex links for laying. It seems like a lot of breeding I know but in my situation I normally use what I have and make the best of it. Do you think the Delaware grand babies will be sexable? Or may their downs be too difficult to tell?
