If I cross a RIR roo with a barred rock hen, I'll get black sex link chicks, right? Will I be able to tell them at 1-day old, and if so, what coloring would I look for in the pullet and what coloring would I look for in the cockerel? I also saw in another BYC forum a reference to crossing a RIR roo with a white leghorn hen (with silver traits). How would I distinguish the sexing of those, and would the sexed pullets end up laying white or brown eggs? I'm assuming white. What would you call those? Would you get sex linked chicks if you crossed a RIR rooster with a black autralorp? All this sexing stuff is so very confusing. Thanks for the help.
