I was in the coop filling food and water, and one of the RSL was staring at the waterer, I had just filled it with warm water, so I knew it wasn't out but couldn't see a reason for her to be just standing there and not drinking . I was watching her to see what was wrong and a mouse popped up from under the waterer, The hen grabbed the mouse and the chase was on. She ran out the door, arround the garden, back into the coop and up on the roosts, off the roosts, back out the door, all the while the rest of the flock chasing her and screeming at her. She had that mouse head in her beek and wasn't letting go. I was laughing so hard I almost wet myself . Finally one of the other girls grabbed the back half of the mouse, and they each ended up with half a mouse. Now I don't think animal cruelity is funny, but would you poke your head out with a big meat eating dino just waiting to eat you .
