I can beat the hard core rooster story!!
I had a legbar rooster. KEY WORD HAD>
One of our nasty blizzards we have in Dec, it was 30 below and the wind was blowing from the NW. Not a night for anything to be outside. The next morning, being a responsible chicken Rancher, I went to feed water and collect my frozen eggs.
I got to the rooster pen and there was a rooster sitting on the roost about 3 feet in the air. just sitting and not moving. I thought I would throw the idiot into the coop. (Each pen has a coop). I went to grab him and he did not move. He was dead frozen to the 2x4 roost. I had to yank him off to get him into the incinerator. Every other rooster made it inside but this rocket scientist of the chicken world.
