Can you house a horse with other animals?

I only have one large stable and a horse can fit in but the thing is I also have a pegasus called Blackjack. He is the same size as a horse but he has wings that's all. Can I house my horse with the pegasus or will the Pegasus hurt him with his wings? The horse is my father's Poseidon, but I'm looking after it for now while he is on holiday
