I am so sorry, but I couldn't keep from chuckling at your donkey's playing with the deceased bird. As long as your donkey has UTD vaccinations I'd not worry to much. Donkeys, for the most part have the constitution of amoured bank vault. More than likely your girl didn't ingest any of the dead bird. We love donkeys here. Just gotta share this: several years back we bought two jennets both in foal by a spotted jack. Both jennets foaled within a week of each other. Watching those babies frolick and play was hilarious to watch. Everyday when I got home from work I'd go out and check on how the girls and their babies were doing. One particular afternoon as I rounded the corner of the barn one of the babies was outside the round corral/pen on the far side of the pen. He saw me and came running/galloping around to me as if, saying "I'm saved, rescued". I opened the pen gate and he flew on those baby legs into the pen to his momma. I checked him all over for wounds, not a bit of broken skin anywhere on him. He had to have slipped through the panel pen some how. Neighbors next door bought him and he to this day comes to visit us. He slips right through their barbed wire pasture fence with not even a scratch. Did I say I love Donkeys!!!
