I have a three-four month old goose, and there are a few things I'm unsure of. Hoping some of you can help me out. I've been feeding her a flock raiser crumble, but it doesn't how long to feed them that. Should I switch her to something else now that she's grown? Like pellets maybe? Also, winter is approaching pretty quickly here. It's already getting pretty chilly at night. What all do I need to do for her as far as winter proofing goes? I hear that they dont really mind the cold. Do I need to provide any kind of heat source in her little house?
