I believe I will be getting 2 Nigerian goats. 2 1/2 years old twins. Wether and an unfixed doe. I finished converting an area in the barn into an 8x8 stall. I made a hay feeder. Now I am wondering what minerals I should get along with baking soda. I plan on giving Grain 1 or 2 times a day in addition to the hay. Hay will likely be 1st cut Timothy. They will have access to a fenced in yard.
