you take the babies out in nice weather and have the parents on one side of the fence the gosling on the other and let them meet, but I'd be real surprised if they would injure the littles geese love babies. But you have to supervise at all times, I'd take mine out and sit with them the adults geese would come around very curious at first then they would start following us me first gosling behind me adults bringing up the rear. One reason i waited till the gosling were 3 weeks old was I was worried more about them getting stepped on than intentionally injured. I tend to be over protective. But by 3 weeks they were sturdy enough and large enough to go out with them permanent. It's such an experience watching the parents with their babies.
