Standing Alone

I have noticed Red has been standing alone more lately. He is not doing it all the time but he is doing it often. I wish I knew what was going on there. It could just be he needs a minute to himself, I do not know. He does not act sick or have any weird symptoms, but he has just been alone more. He let me come over and love on him today and then he went back to his herd. He is a precious donkey, so loveable. I hope he is okay.
