i was hard boiling eggs like i do every week, and i was cutting them up for my chickens and i seen that the center was like orange unsead of a rich yellow like the rest of the yolks. i have been collecting eggs from my bantam ameraucanas tried a couple of times incubating them but with some failure, but what im really asking is does that orange mean some of my eggs are fertile? because honestly ive never seen my lil roo do the deed
