I went out to pour hot water in their drinking water to unfreeze it. I took a few minutes to hand feed some cracked corn and pet the fat little jerks, like i always do. This morning though, the peking was...crunchy....for lack of a better word. Her feathers were a bit frozen. She didn't seem to worried about it...I think it bothered me more than her. is it normal to have a crispy crunchy duck during really cold times?
