A kind old man had a very friendly pet goose the other day at my Tractor Supply. I didn't know people kept them as pets, but the more you learn the better ^^

(Might be weirdly cropped but I didn't wanna post a random guy in the photo)

Would love some recommendations on what to buy as a goose nighttime pen. I’ve seen alot of people use garden sheds but in order for me to get one big enough to house three geese it’s a lot more than what my budget is. Any ideas on what I can buy to build a goose house for At nighttime. Would love to see photos
