Newbie question here.......I am in west texas and the only hay available in the area is Sudan. I have been told not to feed goats sudan because it could cause some problems. I was able to locate some alfalfa last month, but was pricey, 7.50 for a small square bale. The large roll of sudan ran me 35.00. Of course, no one said anything about the sudan until after i bought it. Anyone else use sudan, or any problems with it?
