A few weeks ago, when my hens were still in the old coop, something extremely strange happened. When I let the chooks out, the were small blood splotches/drops on the roof (which opens as a door) a little while later the hens were fighting over a dead mouse, which I snatched from them in case it had eaten rat poison. I wonder if the chooks killed the rat, causing blood splotches or the hens were injured themselves? I emxamine my hens later and found one had a slightly bruised/cut comb. I know we aren't the chicken police here, or detectives, but i was wondering if anyone knew the answer to this mystery.
