Can roosters change the egg color??

[BeckieGoat]

I have a creme-colored coturnix female. She has been laying brown-spotted eggs for two years now.

Her last two eggs are white with teal speckles -a completely different egg.

The male joined us a year ago and has been successfully mating with all the females, but never has an egg changed like this.

He is an A&M as far as I know, but would his genes affect the egg?

I've never heard of that. It doesn't seem likely.

The only effect a males genes will have is the genetical make up of the offspring...50% of the chromosomes from him and 50% from a hen. His offspring may or may not lay a different color egg but his genes do not affect the shell color of the hen it has mated with.....
It will not effect how the shell is layed down around an ovum.
What will have an effect is the nutritional intake, physical condition and age of the hen. When hens are reaching the end of their egg production cycles, they generally, lose alot of the pigment that was being produce in the earlier stages of production, resulting in an egg that has little or no pigment.
Also occasionally, the paint factory doesn't put enough pigment on the shell, causing different colors appearing on the shell, different from what is normally seen day to day.
