well we have an alley way that fits 3 calves perfectly, and when you even have two calves together they are calmer, and the reason i like 3 is you can lead the second calmest one off and tie it and then get the craziest one and take it to the calmer one an dthen go and get th ecalmest one and you can tie it up by the others, and that way you always have a calmer one with the crazy one, and eventully he will settle down. And if we ever have a group of 3 calves all be wild we have 3 donkeys we can put them on ;D hope i helped a little. if you have any other questions just ask
