I agree with Kim in that I would start introducing your new baby to the adults early on. I made the mistake of keeping my goslings from the grownups for too long and now I have to keep them seperated because one gander and one goose act like they want to tear them up through the fence. ( they are just now around 10-11 weeks old). I'm going to try to integrate them later when they can stand up for themselves but for now my backyard is a series of mazes and pens which could have all been avoided if I had introduced them to the geese when they were smaller. It sounds like your adult geese are really coming around. That's great!
