What do you think of them? Can I cross a Dominique hen with a RIR roo to get something similar to a black sexlink? I know that it's normally a RIR roo and a barred rock hen but since they are similar in colors..... Are the wyandottes a hardy breed? Do they winter well? How about their egg production? I'm used to the black sexlinks egg production so I guess I'm trying to compare everything to them .
