I have a duck who I think is about a couple months old. We had two ducklings but one was killed by a weasel and the other one was very badly injured. I brought him in the house and doctored him up and he is doing well. He's very friendly and enjoys his daily swim in the bath tub. I recently purchased three little ducklings because I didn't want Dale to be lonley. He seems well enough to go outside. Should I put him out alone or wait till the ducklings are big enough to go out with him? would it be safe for him to go out alone now that the pen is varmint proof?
