My 2 week old babies will walk up to each other, tilt their heads like they've discovered some flaw on the other one, and then nip the other's face, eyes, feathers, back, butt, etc. They grab a bit of the other's feather, or peck and pull. So far, they do it once, and then walk away. It hasn't caused a problem yet. They also "spook" sometimes, and will fly in a spurt all the way from one side of the run to the other. I think it's just "teen age" growing pains. Any suggestions, insights?
