Can you keep Large appleyard ducks with little Call ducks. I have three 6month old Applyard ducks and one drake, and someone gave me two 6month old female Call ducks. Can I keep them together or will my Appleyards trample the Calls to death. My four current ducks already run over my chickens whenever the chickens get in ducks way. They just keep walking as if they don't even acknowledge the existence of chickens. My friends baby Muscovy ducklings escaped the barn the other day and my ducks almmost killed them by running them over ten times cause the ducklings were following them and my ducks were terrified of them. When are ducks full grown size? Are my Appleyards at 6months full grown, and are 6month old Call ducks done growing? I just don't want my little Calls getting hurt and I also don't want to stress my weirdo Appleyards out as they seem to be afraid of everything that is smaller than them that quacks! The wild mallards that landed in my yard to swim in the duck pool almost made my ducks run through a fence!!
