I have two brush goats, a male( year) and a female (4 years). For some reason, the last several months, they stand at the fence whenever my hubby & I go in the yard/to the car, etc., and just bah/neigh loudly and repeatedly. It's like they're starving or something, which they are definitely not. They have a 2 acre field, with green stuff up to their stomachs & over their heads. They have water. They get pelleted feed 2-3 times a week. They have a salt block. They didn't USED to do this....and it's so annoying, I'm thinking of getting rid of them. Oh, if we go over there & pay attention to them, or give them a treat, they'll stop. But just momentarily. Any ideas?
