Sorry if this has been asked and answered. Here's the deal. I am looking to keep 3 to 5 small to medium sized goats and possibly 1 or 2 sheep. How much of a fenced area is reasonable that I will need. I know I'll still have to substitute some feed for them and that grazing alone won't be enough. I know the bigger the area the better but what would you recommend for 3 to 5 goats and 2 sheep as a "comfortable" living area without completely destroying the ground.
