I have two 3-week old sheep we have raised and bottle fed since a couple days old. They are eating well, growing, running all over and jumping on the furniture! At what point can I move them from my warm low humidity house out to the cold high humidity barnthat is packed with lots of other animals. They would have their own stall. Do they need vaccinations before being exposed to goats, other sheep, horses, chickens, turkeys! I am in North Idaho and it’s cold and snowy. We have babied and spoiled them, but are about ready to have our house back to normal! Lol! How long would you keep them inside your home?
