Junkies are shit, he probably killed it deliberately (or as deliberately as junkies can do anything).

hepatitis

A broken heart

I'm guessing he rolled over on or stepped on the duck at some point or otherwise squished it to death while high.

I assumed that but it appears like a pretty large duck....

Dead junkie weight is pretty heavy, tho

It probably laid down on the floor or something. Probably had a lot of pain from broken bones and internal bleeding before it died.

Was the duck a big guy?

Yes according to his photos, which to me seems like something else

Was killing the duck apart of your plan?

(((Yes)))

By being a retarded junkie

a jiggalo dropkicked it on the way home from a tila tiquila concert
