Guard Geese, Turkeys, and Guinea Fowl for my hens?

[Blammmo]

I have my chickens with 4 African geese in a coop/huge free range pen (about an acre) and I put electric fence wire close to the bottom for digging predators, and a strand at the top for climbing predators.
The geese keep out any flying predators or smaller ones that can slip through the fence like weasels. I keep my pop door open on the coop all night and haven't had problems for over 5 years this way.
The outdoor waterer is next to the pop door so the geese sleep under it at night which I'm sure helps.. Noisy but the only time they get a bit agressive is mating season, the rest of the year they follow me around and beg for handouts

I have about many layers in a closed run but we are adding goats and guinea fowl this year. We are also planning on some free range meat chickens with the goats. I love the idea of adding geese but I’m afraid they will attack my small grandchildren. Any thoughts?
