Feel a little silly asking, but it just occured to me to make sure my pipe corrals would contain calves. I plan to let them out in larger fenced area but basically to keep them up at night in my pipe corrals. I've had full grown sheep squeeze their way out of the corrals, but I think calves wouldn't be quite so...determined? I also have mini-donkeys. They can be separated (have several different corrals) but am wondering how they may get along? They were with a 6 month old calf before and everyone kept to themselves.
