I thought I would just look at jennies (females), as we have had so many bad experiences with mean male livestock--from horses to goats to turkeys. Interestingly, the first ad I read included this description: "Sweet, gentle and a great mom! Great guard donkey or companion animal too. She will trample and go after anything unusual or NEW that enters the pasture including newborn goats or lambs. . ."
Try as I might, I could not get the "sweet" and "gentle" to go with trampling newborn goats or lambs. I hope this is abnormal behavior. If not, I think I'll give up on donkeys and get a calf of some sort. Maybe I should start by researching feed consumption. There's just about no grass left in Fiona's pasture, and hay is expensive because of the drought here in Texas. I sure don't want to buy something just to keep Fiona company that's going to eat its way through my pocketbook. I should have known there wouldn't an easy solution. Any thoughts, recommendations are welcome.
