Sometimes the donkeys can be bossy.
This morning Lulu pulled her ears back and chased all the sheep away from their feeder. Then she pushed the hay out of the feeder onto the ground. All the animals love the pieces of hay that fall to the bottom of the feeder. So once Lulu has gotten all the good stuff, she moved back to the other feeder and the sheep came back to eat leftovers, which is actually most of the hay.
Sometimes I try to intervene, but I rarely can make a difference. So mostly, I just let them work it out themselves.
