I am in the middle of a hatch. The rooster was EE, and the hens were EE, RIR, BR. The BR chicks are all proving to be typical sex linked birds. I'm noticing that the RIR chicks have hatched with over all yellow down and minimal chipmunk pattern OR, overall light brown/red down with darker chipmunk striping. I'm guessing that if I knew which was which, I would be able to sex them with 100% accuracy. Any experts out there? Also, one of the EE has much brighter coloring than the others. The gal who donated the eggs is guessing that one is a rooster because it matched the coloring of her rooster as a chick. Any one out there care to comment about the EE/RIR chicks, and the accuracy of sexing them? I'm taking an uneducated guess here and thinking they follow the red sex link pattern?
