Goats who have free run of a pasture or yard can do well with enough shelter to keep the elements off and provide comfortable movement and space for all of the goats when inclement weather or intolerable sun hits. As long as they have the freedom to go outside as needed, this will be fine. If they are cooped up and unable to go in and out on their own, you must provide more indoor space. Goats who need to stay indoors a great deal due to inclement weather or other reasons need approximately fifteen square feet of indoor space each.
