Trying a new cross.

Yesterday my broody hen gave up sitting on the eggs she had stolen. Most is my hens are rsl and a some rsl crossed back to a pure heritage rir. Now they have a pure white rock roo in with them. I took the eggs and put them in the bator to see what I get. Just wondering what you think will come from the rir/rsl cross mated to the white rock roo. I know they will be mutts but in hoping for some mostly white birds as I only have a few white rock hens. I love my mutts. They lay great and are always calm good birds.
