New Chinese Geese

My neighbor got his pair last year, they had babies which are probably about 10 months old now. I guess the 4 of them were fighting so he asked if I wanted the babies. So he caught them and put them over the fence, now however, they are all glued to the chain link fence. It's only been about 3 days, but I want them to explore the yard, and they won't leave the fence line. My neighbor now wants to get rid of his two, but if I take them I feel like they're going to fight again? Any advice on if this will change?

 

Thank you. I did find a home for the older two with a good friend. Hopefully all will be well after they are separated.
