I have an Ameracauna, or I presume, Easter Egg rooster. I have a variety of hens but have only been collecting the eggs from my Black Copper Marans. What are my chances of getting Olive Eggers? My rooster has to carry the blue egg gene right? Are there any physical characteristics to look for or do I just wait and see? I recently hatched 2, and have more in the incubator now so I know I have a wait ahead of me until we see an egg and the suspense is killing me.
