Hi. I am aware that geese require very little compared to chickens when it comes to housing. What I can not find information about is how much space they will require. Specifically, should they be able to stand up completely in their house? My geese will only be housed at night, or when they feel they want shelter. Otherwise they have a large area to safely roam at their leisure. Thanks in advance for any input! I have 2 Embden geese.
