Agree, SQUIRT BOTTLE works great for correction purposes, one that squirts a stream as far as possible. When your Roo starts to approach you with that look in his eye, squirt him. He'll learn the bottle & keep his distance. Works great for my Pullets, when they get too close to one side of your property (fenced but neighbor's 7 dogs). There are times I even use the garden hose, thing is they know they don't belong close to the fence line but just get curious. I walk out the door & if they see me pick up the squirt bottle or hose, they beeline away from the fence. Smart chickens, like kids got to keep testing us....
