Thanks for the advice. He is currently with two mini-horses who are bonded to each other. He will be coming to a situation where we currently have 5 horses which are pastured as 2 horses together, and the other 3 together but of these 3, 2 are about to leave. I am hoping, with the right introductions the horse who will be alone and the donkey could become each others bond.
I do have an equine vet that I know also deals with donkeys and mules.
I did discuss his current health. He has been vet checked and is healthy. Also discussed diet. He is currently pastured without supplemental food. Rescue told me that his dietary needs are different from horses and he does not need anything else while good grass available, and hay during other times. It would be the same situation at my place.
I read that donkeys need coats more than horses and ponies. We blanket ours if it is cold and rainy, or cold and damp snow. I am also in Eastern Ontario so MACCanadianCoop knows my weather. Do you blanket yours? Sure hope I could find another one a cute as the one on my pony in my avatar.
