I'm thinking of getting some geese, but I've only ever raised chickens and ducks before, so I have a few questions. First, is it true that all they need is a three-sided shed for shelter? Won't raccoons, possums or skunks get them? Those are basically the only predators around that I have to worry about, besides possibly a wandering dog. We do hear coyotes sometimes, but I've never seen one around. Would the geese really be okay not locked up at night? Second, do they do okay free-ranging in the same area as chickens? I'd give them a separate house, but it would be near my chicken coop and I'm sure they'll interact with my chickens as they range. And third, is there any breed that is non-aggressive? I've heard bad things about aggressive geese, and I have small children. Of course, they wouldn't be allowed to chase or harass the geese, but they will be around them and I don't want to take any risks. Is there a breed that's known for being calm and easy-going?
