We have 2 Cayuga ducks - 1 male and 1 female ( there was 3 female then a fox got them ) and 4 Guinea hens. I'm going to attempt to incubate some of the females eggs and hatch some. But additionally I want to add maybe some silver apple yard ducklings or Rouen ( or both ) and possibly 3 female chickens - Easter eggers. Any advice / tips? Al the new ones would be babies.
