I recently bought a lovely little Olive Egger pullet. Here feathers are coming in beautiful partridge coloring pattern and she is very sweet.

I've had her for about 1 1/2 weeks and she has a single comb like my other pullets (Australorp, Welsummer, marans etc.) I have since read that the blue egg gene goes pretty much hand in hand with the pea comb. Can the blue gene come with other comb types?

Here's more info on the parents

Mother -Olive Egger (Welsummer roo X EE hen)
Father - Black Copper Marans

The mother does lay olive eggs but I'm wondering if my little pullet has a chance of having a blue/green egg gene or should I be expecting a brown egg?

Thoughts?
 
It has to do with where on the chromosome the blue egg gene is located. It is right next to the gene for pea comb. If by chance the chromosome splits a tad more one way than the other during fertlilization, the blue egg gene can be passed on without the pea comb. User name on here "Kev" has an entire flock of blue egg laying turkens with single combs! My friend had a blue laying hen with a single comb, so I know it can happen. Every time this discussion comes up the serious genetecists on here say 3% chance.
 
@ onthespot. Wow only 3%. I was hoping that it would be better than that. I guess that a basic square would be something like this?

Which I guess means it's all browns with a 50/50 recessive blue chance. And the 3% is taking into account the wildcard factor right? Well, I'm shooting for a beautiful egg basket and she'll add another shade of brown which is still beautiful and who knows... maybe a few speckles in there somewhere

Thanks for the numbers.
 
Maybe this little 'brown egg layer' will end up laying a more consistantly even brown egg that my BCM since there is some Welsummer in her. I'll let you know in 4 months
