So my Lavender Orp was dirt bathing today and I couldn't help but notice that the Copper Blue French Maran was pecking at her and scratching on her body as if she would scratch the ground for worms or something.....IS THIS NORMAL?! Lavender Orp was not bothered by this whatsoever. I've only been free ranging chickens in the city for 2yrs now and need your expertise on this, thanks!!!
