The local TSC has in stock a mineral block labeled for goats and loose minerals labeled for cattle and goats on pasture. Does it really matter which kind I use for the 2 nubian does I am getting this weekend? They are going to have a little over an acre of browse fenced in. Feed will be last year second cut hay and first cut hay from this year. Also the are that they will be fenced in has a few places that is very wet, is there anything I should do before they arrive to help keep possible worm populations down?
