off my rocker

This is what chicken-tending will do to a person.

I just got an email from a farm supplier offering a free "vent opener" with purchase. So I thought, Wow, under what conditions would I need to open a hen's vent? Would I really need an instrument for that? Also, ew.

My imagination was completely running wild at this point, so I went to the site. Here's a vent opener.
