This is a plot hole that really annoys me, no it's not how Arniel can carry Keening or even how the hell did the Dwemer put the Oghma Infinium in the box. No, it's much more shocking and completely destroys the lore.

Brace yourselves...

If you can cook Chicken recipes in Skyrim.. how come the only way to harvest Chicken leads to having an army of pissed off guards killing you?
