Quote: I would think that cross would keep the color until end of season... I used a Blue Copper Marans hen covered by my Ameraucana Roo. We'll see if she stays laying this nice color, although I'm sure it will fade somewhat. Funny, one of my Easter Eggers that has a more olive colored egg just laid a really deep color again. If she wasn't in another pen I would have thought that was my OE laying! Guess that's why we separate if we want to know for sure, but I really wish they could all free range. I think someone mentioned that the Olive Eggers second generation won't keep the olive egg. I have her in with the Marans so I'm hoping that will keep the dark. Then stick that hen back in with the
The reason they say the second cross to an OE won't keep the olive eggs is that the hen and rooster from the OE cross have one blue and one white egg gene. Brown eggs are genes that coat over a white egg base. Crossing that would give you the possibility of green or brown eggs. I think its 50/50 - but because the brown eggs have more than one gene they may be lighter than the original cross if they loose some of those genes as they only have one copy of them too. If you cross to the Marans you will probably keep the dark, but you may loose the blue. Going back and forth will work for half the kids.
Oh....a white gene...OK! Wow, I won on the 50/50! Actually better because I only got one OE and she kept the white gene? If I don't go back and forth is the Olive egg lost? So I need to move the Olive girls, then their babies, then their babies back to the AM? And still get 50/50? Or....put the OE/BCM directly back in with the AM roo?
