These are 6.5 wks old. Black copper marans excepting the white one which hatched from a marans egg. The lady I got them from also dabbles in olive eggers so I'm guessing this is a 1st generation OE. I also have a wheaten ameraucana that is a roo too so from my hatch, I think I have 4 out of 5 being cockerels. If that is the case, I'd like to know sooner than later so I can start hunting for some replacement chicks... This is the OE, I would guess Roo based on comb/wattle Marans #1 I think is a Roo Marans #2 I think is a Roo and Marans #3 I think might be a hen excepting her saddle looks suspicious and she is colored exactly as the other two. Please let me know what you guys think! This is my first attempt w/ chickens.
