I dunno, my goats scream everytime they see people, any people, expecting to be fed.They even see us when we are in the house and scream. They are not undernourished by any means, they just demand things. I think from previous posts, that is what goats do, although I believe some breeds are worse than others. My dairy goats are the worst, my boers, not so much. My one neighbors goats do it too, but the other neighbor, they do not make a sound but I think thats because they are fed so mcuh they can't move. Seriously, they are way over fed.
