Hi guys,
Does anyone know what to mark when one of my birds is grey. Not green grey.
I have tried everything.
I know something is wrong cause blue cock X grey hen suppose to be 50% grey 50%blue.
In fact I get grey green chicks...

By marking grey, you actually mean just the grey mutation, i.e. a grey green bird. By marking grey and blue, you mean grey blue or the bird that looks grey.
