Until you have paid for the item, it is not your property, so it could be theft.

However it would also be difficult to prove theft, against a halfway
competent brief in a magistrate's court. "Theft" has a very specific
meaning (look it up, it's really very narrow), and doesn't cover this.
Of course if the defendant was before a jury, they'd be unlikely to
have sympathy for a legal nicety like that.

If anything, there would be a stronger case for criminal damage to the
chicken leg.
