Now I get it! My silkies are only pretending to be sweet puffs of fluff. They are waiting until they have me in their power, with my back turned - then they'll attack. No wonder they are such good broodie hens - they are hoping to take over the world.
Beware! Must secure silkie pen. Too late! They have been given free roam of backyard. They have infiltrated the safe zone. They have recruited the other chickens to their plan. There is no hope.
Wait! Up in the sky! It's a bird. It's a plane - It's the RED TAIL HAWK!!!
There is still hope.
