well the effect I heard is that even people who don&#x27;t buy the chicken (ever, they just aren&#x27;t chicken buyers) buy more of everything else due to the smell.  So the store doesn&#x27;t need to sell any at all, it just needs to be there.  Though come to think of it this actually wouldn&#x27;t affect price (because that smell effect would hold true if it&#x27;s too expensive, right?) so perhaps it&#x27;s a combination of both your effect (which affects chicken buyers) and the one I heard about (which affects non-buyers).
