Hi EmAbTo48... a unique name I would say. If the momma goose or another female is around there should be no problem putting your feathered young with the crew. I raise geese as well as ducks and chickens and have put incubated gosling with the pack all the time. The only thing I would keep an eye out for are the males at times.
I have had a jealous male get nasty with goslings before but very rare. Most of the time the males will be just as protective over the goslings as if they were his own offspring. For that matter I have had geese raise ducklings as well without any issues. I have Embdens, Chinese, Pilgrim and Toulouse and all 4 breeds are good with new goslings and as I said good with ducklings as well.
Give her a shot and you should see a positive acceptance unless momma goose is setting on eggs. If you have a goose setting she may leave the nest to care for the other youngins. If not setting then it should be OK. Steve
