I have 8 runner ducks. they are in a fenced area in the yard have a small pool for water and 4x4 shelter it is wood frame hardware cloth sides bottom and top with tarp covers over that for shelter from wind rain ect. I am in tenn coldest it gets here is the teens at night and that is rare is this enough shelter for them? they have wood chip bedding to snuggle in and the pool is across the area so it stays pretty dry
