@eleanorkonik Depending on context, donkeys and llamas (!). Mules, I think.
Also, some guard animals will successfully fight off the expected predator, some just make a lot of noise failing to fight off predators. Roosters are like that in rural places IME -- despite their armament, they rarely survive a battle, so they're a bit of an ablative shield. Keeping a couple of backup roosters requires separate pens.
