All our horses love our donkey and try to protect him but they don't really attack each other over him, just the ears go back😂
Note that they literally love each other when Ghost , the donkey, isn't around.
Separate them with fence in between until they get used to each other!
Hi Isabel I would say maybe try putting your horses in a field next to each other with a fence imbetween then when you start to see improvements bond them to be able to be with each other. I really hope this helps you :-)
