He had a bunch of super fine downy feathers under the frizzled feathers and I swear they multiplied in number as I plucked them. And his carcass was quite narrow, making it really, really hard to me to get my hand into the cavity to extract the organs. I think I was also just way too tired to process a bird today, but with a very long to do list I plowed ahead anyway.
I also noticed his carcass, despite his age, confinement, and my attempts at fattening him up...he had almost no fat on this body. I'm assuming it's because of that higher metabolism that frizzles have. Wish I could borrow that trait from them.
