Wow that calculator blows my mind. Unfortunately they weren't my eggs, so no guarantees in terms of parent birds.
These are the chicks, you'll see the 50/50 divide!
Hi
I have hatched ten chicks from warren hen X cream leg bar cock
5 are solid yellow and 5 are chipmunk stripe
Might is be possible that this is indicative of gender as they would have similarly autosexed if pure? Or is this completely unreliable
