My chickens come in large and small sizes, and then there is the cockerel with his resplendent tail and wattles.
They are provided with a short steel rod which pushes into the ground, and the chicken leg slots over the rod, holding her in place. That makes them easy to move for mowing, or to reposition. A large part of the fun of owning them is to be able to find them new patches to peck from time to time.
Large hen £125

Cockerel £175
