It makes beautiful Olive Eggers. I have blue feathered Olive Eggers and love them.
I crossed a blue Ameraucana hen and a very light feathered Golden Cuckoo Marans roo.
I have crossed many different roos in both EE and Marans with hens in EE, Marans and Ameraucana to see what different combinations of feathering I would get and the eggs are such a fabulous addition to my egg cartons.
Not to mention some fabulous looking hens. The roos have enough meat for eating, too so none of my projects have gone to waste.
