My DW has prevailed and Puff daddy is out on parole. He is usually OK but he wakes up with an ... attitude, and so whnen I let them out for the day it helps to either supervise for a short while, or let him out of the run while the rest remain in the run for breakfast.
He has some good qualities, for instance he is not a pig about treats. If I throw him a berry he starts picking it up and dropping it, clucking all the while. Of course this behaviour invariably draws a few pullets who dash in to grab the treats.
