A couple of weeks ago, I was in the barn pitching hay when one of the hens darted forward at something. Whatever it was must have disappeared since she stared intently for a moment or two, then walked away.
A few minutes later another hen darted forward... and this time she snatched up what looked like a mole.
She proceeded to bash the poor little thing against the ground, then pecked at it viciously.
In moments it was quite dead... and then she ate it.
Chickens are far more carnivorous than we give them credit for. We all know they eat grubs and worms and other things they find. But a small mammal? That one surprised me.
