ISAs that were crossed again. So I bought 10 pulleys off of the seller, 5 white and five red. I was told some are a combination of RIR roo x ISA brown pullet and the other half are ISA brown pullet x ISA brown roo. So I guess they are considered 2nd generation ISAs so they no longer are sexlinked... which is a shame because it really would take the guess work out lol
Thanks...
I’m on the fence now on this one. I’ll still give it the benefit of the doubt here and say pullet.
