Aziraphale gives the little wicker chicken a fond pat on the head regardless of the fact that it's quite inanimate, and seemingly determined to remain so. "Sagramore's got a chicken?"¹ He may as well crack this bottle of apple wine he's holding, since he's here! He produces a corkscrew from the pocket of his jacket². "You ought to donate this for its coop. As decor."

¹He doesn't go outside much.
²It definitely wasn't there before, but he's pretending it was, for the aforementioned "it's rude to conjure random objects right now" reason.
