I am new to olive-eggers. I didn't know about the single comb. I keep getting told that they think all 3 are boys. I am going to be very sad if all three are boys. That would be some terrible luck.
I am too, but the middle one has a small, light comb. So far, looks like a pullet. I hatched seven OE eggs and five look to be male. One is female and the one with the single comb looks to be female. I'll keep her, if she is. She will lay dark brown eggs.
