Geese are good foragers in the summer, but when there's snow on the ground they need a dry place to sleep, and you will have to feed them some grain. I haven't had geese for a while. I used to feed them cracked corn, and alfalfa pellets in the winter (The kind they feed to rabits). Plus they used to pick up what scraps of grain the horses left. If you can find some really nice leafy alfalfa hay, they will pic the leaves off, but there's a lot of waste with hay. They will clean up the pelleted alfalfa, and nothing goes to waste. Good luck.
