Confusing egg color-recessive gene?

[gonehencrazy]

This spring I hatched 3 olive eggs. The dad is a French copper maran. All three were girls. One is all black, the other two have gold necks. Two of them are laying. Raven, the all black, is laying brown. Her sister is laying army green. It shouldn't be possible for Raven to lay brown eggs should it?!

There is no gene for olive or green egg colors. The most typical method of creating olive eggers is by crossing a dark brown egg layer with a blue egg layer. Those F1 generation olive egg layers will each have one white egg gene (from the dark brown egg parent), one blue egg gene (from the blue egg parent) and various brown egg genes (from the dark brown egg parent).

Since you bred the olive egg layer back to a dark brown egg layer it is very likely for the offspring to lay brown eggs. The hen that is laying brown eggs apparently got the white egg gene from her mother and father along with various brown egg genes from both parents. Your olive egg laying hen got the blue egg gene from her mother along with a white egg gene from her father and various brown egg genes from both parents.

It will be interesting to see what #3 lays. I think she’s getting close.

I knew #3 was close to laying!!
