I've got 4 or 5 chicks hatched today from Ameracauna roo x with hybrid red layer. Are there any tricks to telling gender by colour with a cross like this? Purely for education reasons. They will all be grown,not killed as babies. I also have 2 Ameracauna x Ameracauna. No idea which is which, my Ameracauna girl is black. The roo was reddish.
