I am looking for 2-3 duck hens for a friend. Her son is allergic to chicken eggs so they would like to add a couple of ducks to their coop for him. Would prefer breeds that are known for their excellent egg laying abilities, so they are more likely to lay most of the year. Indian runners or Khaki Campbells are probably her best bet. Prefer ones already laying, but would consider this years hatch also. Must be reasonable priced also, thanks!
