I bought 29 cows from a Lely robot farm and trying to train them to go through our DeLaval robots. They are starting to do better and several are going through by themself and the rest are starting to go in better. The problem with pets they sneak up behind you and rub there head on your back and give you a shove or come up and want there head scratched. The biggest problem with them is if they don’t want to go where you want them to they ether just stand there and not move or just walk over the top of you. Other than that they are nice cows but I hate to work with tame cows.
