Choose white or the lightest colored eggs to hatch if you want blue laying pullets. The darker eggs will produce green layers. Hope you get a bunch of "pretty egg" layers. And pretty "egg layers"!
Also, is your EE male from a hatchery? They tend to be more consistent keeping the blue gene in their stock (but it can still vary). Some backyard breeders will "make" their own version of an EE, sometimes outcrossing, and the genetics can actually be more varied than hatchery stock... the downside being your male might only have one gene for blue shells making it 50/50 whether it gets passed on. Hatcheries have been fairly consistent for at least 30 yrs (when I got my first EEs).
I purchased both from a feed store so probably hatchery? I can ask where they order from.
Both ee's have pea combs. Will this improve my chances of blue egg laying off spring? Still pick the lightest colored eggs?
