Hey everybodywill a Leghorn roo x rir hen be able to be wing sexed? I have 39 rir hens but want to cross it with a fast feathering roo to make it easier to sex them....

Hey there.
I believe the first gen offspring would, indeed, be feather sexable there. Leghorns being fast feathering, RIRs being slow, that should do it.
There used to be someone on here who knew tons about this, but I think @Chris09 isn’t here any more?
Hopefully someone more knowledgeable can chime in.
