Can a mod move this to the Goose Section? Geese bond strongly with their human caretakers if raised properly. Check out this website for information on geese and human bonds http://www.thegoosesmother.com/id27.html
I'm not sure how they will act during breeding season but I'm sure they'll stay friendly toward you at least. They tend to be protective as adults. You should just do some training on being gentle and be around them a lot and they should do fine. Hopefully this website can help you out!
