I have a newly-hatched Canadian Gosling. It is so adorable and sweet, and has already imprinted. It has an enclosure that should be finished by today. The only problem is food. No stores near me sell Goose Feed, and I did some research and was wondering if I could feed it Chicken grain scratch and chopped greens like lettuce, with maybe some added crumbled egg yolk. What should I feed it? It loves to eat anything green.
