Cuchoo Morans???

I have a connection to pick up some of this breed and don't know about them. What can you tell me about this bird. I have my first flock of hens that are about 8 months old am thinking of adding to them. The birds available are 4 months old. Are these hardy birds, good egg layers, what color eggs? Do well in all climates??? Four seasons where we live out west. Do I need to keep them separated in a separate pen for a while before introducing to existing girls? If so, how long until I can turn them loose? What does this breed look like? Thanks for all the answers.
