As a rookie goose owner I had a question. I have 5 geese - 2 Chinese, 3 Pomerian Saddlebacks. They are about 3 months old. They range close to my house during the day and at night I put them in the 3 X 8 chicken tractor to protect them from predators. To my question: is there ever an age/size these geese will be where they are no longer in danger from raccoons. I'm wanting to put them in my uncovered chicken run at night after the hens are in the coop. It would be easier herding them into it than the tractor. They'd be safe from coyotes but obviously raccoons can scale the 6' walls and get into where the geese would be. Thoughts? Thank you!
