    I have 5 EEs that lay 5 different shades of blue and green eggs. My rooster is a Brahma. If I cross him with my EEs, what are the chances of their offspring laying blue and green eggs?

    You'll likely have green eggs if you cross them with him, no blue eggs from the offspring. There are two shell colors, white and blue. A brown egg is a white shelled egg with brown pigment. A green egg is a blue shelled egg with the same pigment as the brown one. The blue shell color is a dominant trait over the white shell color.

    O - blue egg o - non blue egg
    One parent x other parent
    OO x oo = all blue egg layers (heterozygous for the gene)
    Oo x oo = 50 percent blue egg layers (half heterozygous for blue and half with no blue egg gene)
    oo x oo = no blue egg layers
    OO x OO = all blue egg layers (all homozygous for blue egg gene)

    Thanks for the info. It will be fun to see how it all turns out. I plan on incubating some eggs from each hen.
