I have a friend who has a 4 week old gosling. She lives in a residential neighborhood and has had a goose who died at Chritmas time. The gosling will live outside in the backyard. She takes the gosling outside now to run around an socialize her. She will not be in a cage or have a coop, just a sheltered area like a dog house. My friend wants to know when is it safe to turn the gosling out in the backyard permanently? Thank you so much for your help!!!
