Staff from a Sainsbury’s in Redditch discovered a distraught cockerel dumped in a bin bag with gaffer tape around its head and beak, the RSPCA said.
Employees spotted rustling coming from a black bin bag in the supermarket's recycling area, which has become a hotspot for fly tipping.
Upon opening the bag, they discovered the frightened black cockerel, which may have been used for cockfighting before being dumped.
