Ate it. They are voracious mini t-rexes if they get a chance.
I’ve seen them eat frogs, salamanders, newborn chipmunks, and even a hummingbird…lol. The hummer hit the window and was either stunned or near death and the chicken found it. I chased after it, but it ran to the other side of the yard with it and after a certain point you just let them do what they want with it to take it out of its misery faster.
