I have a 12x16 garage that has 9 feet portioned off for my chickens. The remaining 11x12 probably could house 2 goats comfortably. The winters here are harsh and can drop down into the -30C range. Im concerned for the health of the animals. The barn has no electricity and no running water. I have to bring the chickens water in the morning and evening. So i would need to do the same for the goats.
