Hi all. I have some EEs (sold to me as Ameraucanas, sigh) who lay both mint green and tan eggs. I'm not interested in the tan. Could someone tell me the genetics of blue and tan egg colors? I know green is blue+tan. I'd like to breed out the tan, and be left with blue eggs. Green are fine too - I'm wasn't sure if all green-layers also lay tan (since it's blue+tan) or if a hen can lay all green eggs only, or green and blue. Also, if I have a roo that has genetics for white eggs, what would I get crossed with a green and tan layer? Does that help or hurt the process of getting rid of the tan? Or does it make no difference? (I currently have no green or blue genetic roos, I'll keep one from next generation.) Is there such a thing as a blue and white egg layer? Or is blue a modification of white, separate from tan? Are you more likely to breed out the tan if you only select green eggs for hatching, or does that not make a difference? Thanks!
