Geese aren't friendly unless you raise them from chicks, then they won't let you go. I've never met a goose I could pet, and got plenty of bites and tongue-hisses. Ducks are smaller and cute. They are more skittish, though they will get used to a safe friendly presence. Ducks have tastier eggs. Geese will taste you if you try to take an egg. I once had a pet chicken that would sit in my lap and be petted but now "they" say not to make pets of chickens because of salmonella...
