Any one know where to find fkn feathers?

I have committed myself to finally stop saying the bow is shit because I can’t one-shot every zombie from the moment I get one. Trying to craft some improved iron arrows and I need feathers. I’ve got a few hours in this game now and I’m pretty fkn sure I’ve never seen feathers.

On the other hand I’m wrong about things with staggering frequency.

Any one know where to get feathers?
