The size of things they can swallow always shocks me. My smallest hen who is probably only 3.5-4 pounds managed to eat an entire vole whole. Pictures of the chase (barred one is the small one)…Two of our BO hens each found a toad the other night. Both ate them and the one hen I thought was going to choke to death in the attempt did not. She did pause and grunt for a moment and I went to get her to pull the toad out BUT…..too late…..down it went. The unfortunate toad was about this size.
