Yes. I have a flock of over 50 chickens housed with 20 ducks, 2 geese, 14 guinea fowl, and 2 rabbits. All get along together with no problems, but my run is LARGE (100'+ long & 20+ wide). Just know that ducks will befoul any waterers they use. I change all my waterers daily in addition to filling basins and stock tanks for the waterfowl.
Do not brood chicks with ducklings or goslings, however. The latter two grow large even faster than chicks and they will create chick pancakes if you try to raise them together.
