This is my first time weaning a horse and I need help. I have had to start weaning my 6 month old mini donkey. He was getting to aggressive with his pregnant mom. He is in another pasture with our big horses, but he paces up and down at the gate that goes into his moms pasture. He has lost his voice from calling to her so much. I tried setting it up so that they couldn't sniff noses, but he was getting to stressed out with that. So I decided to set it up so that him and his mom can touch noses. He still isn't calming down. Any advice?
