I have some 5 week old BLR Wyandottes that are throwing me for a loop on their sexing! 2 of them appear to have a single comb instead of the rose comb. I only know how to tell difference sex in combs when they are actually the same type of comb. sigh. Are there other ways to tell this young? I have a sinking feeling I am looking at a lot of Roos here. Can anyone give some expert opinion on these? #1 Zipper #2 Freckles #3 Pico #4 Peanut (a nice Splash?) Thanks!
