We have a bottled fed lamb that has been weaned and eats hay and some green grass. Every day he usually goes crazy eating like constantly. But today he will eat when I come around and when I give him green grass, when I leave him he just sits down. Just something is off about him today not sure if is just the weather like a storm coming or if there is something wrong with him. He is pooping and peeing and chewing cud just not himself. Any ideas could be I'm just being wacko?
