I found a mouse that had fallen into a plastic bucket in my coop and couldn't get out. I felt bad for it so I took it out into the yard and let it loose a few feet from the fence, thinking it would zip through the fence and be gone. It did start trotting toward the fence, but before I knew what was happening my little Buff hen, Portia, came zooming out of nowhere and zeroed in on it like an F-16. She grabbed it, smacked it on the ground a few times to kill it and then ran off with my other 4 hens in full pursuit. Even though she's the low man on the totem pole she would not give it up and eventually ended up with her prize. I didn't stay to watch her eat the whole thing but she was really going at it. Yuk! I tell people that my chickens will eat anything, but that surprised me.
