At the top of this FB group page there is an excellent chart for OE's,
and great place to ask questions.

Might take awhile, not sure who's admin these days.I requested membership, just waiting for approval... The chart doesn't go all the way to F4 but I will ask them, thanks!
Your whiting should of been pure for blue eggs so it had two genes for blue. Marans are not carrying blue egg genes so they have two copies of non blue (white)
Your first cross gave you one blue gene and one non blue gene. Blue is dominate so even with one copy of the gene the bird lays blue eggs. Of course you're bringing in the marans brown to make the blue to green (olive)
Here's the problem. Marans don't carry blue. So offspring will only get non blue from them. Your crosses carry one blue and one non blue. Therefor everytime you cross back to the marans the offspring produced has a 50% chance of getting the blue gene and a 50% chance of getting the non blue.
So about half will lay green and half will lay blue.

So you dont think a dark olive hen crossed with a Splash Copper Marans will yield a chick that will lay brown?
That would be great if the offspring will lay green or blue!!
