My neighbor bought 10 geese today. I am not a goose man because I don't have a pond so I have never raised any. The geese are all 3-5 months old. The lady he bought them from said to take them to your pond and throw out some food and turn them out. They did and when I came home this evening I saw them all in another neighbors field about a mile from there place rounding up geese. They found 8 of 10. They brought them back home and keeped them penned. How long should they keep them penned? Sorry I don't know the breed. 2 are Africans and the other 6 are white.
