What are some of your must haves?? We only have 2 goats (Nigerian Dwarfs) and do not plan to breed/milk/show and we do not plan to have a goat farm or anything. Simply, just these 2 goats. (might add 1 or 2 later on but no more). What are some of the thing I should keep on hand? it would also be helpful to know what the item is used for....all new to me and still trying to learn!! TIA!
