Recently, I adopted two orphaned foals. The older of the two: Legend has gotten to biting, kicking, and pinning his ears back when I do something he doesn't like . . . Even if it is just moving around him when he is inside the shed. I think it might be because the younger foal: Finn tried nursing off of him. Any ideas on how to get Finn to stop attempting to nurse off of Legend and stop Legend from biting and kicking before it gets too serious?
