Unfortunately the wheaten (all three-wheaten, blue wheaten and splash wheaten) eggs get lighter in color as they lay. Normally they start out being a light blue, then fade to an off white with a blue tint, then later lay white eggs. We have had a very few lay pink eggs. None of the pink eggs have been hatched. The pullets that have laid pink eggs have all been sold to someone who wants layers to produce eggs to eat. Either 3 or 4 years ago, our bluest egg from a pullet for that year was laid by either a wheaten or blue wheaten pullet!
Back to your original question. I didn't think at the time to tell you that splash wheaten pullets will have white in their wing and tail feathers. There will not be any possibility of you having a splash as none of our pens were set-up to produce any last spring.
Presently we have two breeding pens set-up which can/will produce splash wheaten, with at least one more in the plans.
One is our #+3W-2016 which is a splash wheaten cock and a blue wheaten hen. They will produce (on average) 50% splash and 50% blue wheaten chicks. The other breeding pen is #+4W-2016 which is a blue wheaten cock and 3 blue wheaten hens. They will produce (on the average) 50% blue wheaten, 25% wheaten and 25% splash wheaten chicks. The bad thing is the chicks cannot be determined which they are at hatching, as they are all the same color at a day old. When the chicks are about 2 weeks old, the first chick feathers on their wings and tail will let you know whether they are wheaten, blue wheaten or splash wheaten. Wheaten will have black, blue wheaten will have blue and splash wheaten will have white. The wheaten varieties (all three) are a lot of fun to raise as they go through many changes from hatching to maturity (show ready)!
