That is a good point. Its an older pasture so it is mostly orchard grass, alfalfa, and clover but since it hasn't been used for awhile, i'm not completely sure what else has made its way in there. No trees but I'll have to take a look around.You need to make a list of all the plants in the pasture and figure out which one the goats aren't doing well with, I think. That's my first guess.
What kind of grass? Forbs? Weeds? Tree leaves they may have been eating?
