Your last two hens you showed are splash cuckoo.
The red breasted blue girl is the one creating your duckwings - She's a duckwing w/blue.
Your first pen will create a bunch of mixed up splash and splash cuckoo birds with odd gold leakage on them.
Your second pen will create a lot of blue,normal, and splash duckwing looking birds.
Your third pen will create more sex-linked blue cuckoos much like the first pen as well as some duckwing colored ones.
Your fourth pen will, in theory that the "white" one is also a splash cuckoo? - A bunch of and splash blue cuckoo birds with a lot of gold leakage.
If he's actually a true, pure white - You'll get a bunch of mixed up colored birds. They'll look like EE's, granted if the white is dominant.
So, I think your second pen is the only one to create standard colors. The only standard colors you can create in this big jumble are duckwing and white. (pair the white with the splash cuckoo girls and bingo)
To answer the chicken calculator question - There's a website that helps a little, but doesn't "explain" the genetics.
