Hey guys! I have 11 chickens, 6 Buff Orpingtons and 5 Barred rocks (one was killed by a coyote). My daughter wants to get a couple Rouen ducks. Is it possible to get a few Rouen duck eggs and have my chickens incubate them naturally? My husband and I really don't want to have to build another coop but we have heard of chickens killing other new birds in the past? what should I do!!?!?!?!?!?!?!??!!? thank you sooooooo much!
