I observed my "top o' the ladder" RIR ("Buffy") being tended to by the other two (RIR and EE). When I say "being tended to", I saw "Buffy" as she stood in front of the reflective sliding glass door while the others delicately picked the remnants of poo from her fluffy butt. "Buffy" seemed to enjoy the attention. I've seen them preen each other's feathers, but not this behavior of two tending to one. Is this typical? Has anyone else observed this in their flock?
