An animal welfare charity is appealing for information after 14 hens were found dead in a dustbin near the Carron Valley reservoir.
The Scottish SPCA was alerted by a member of the public who made the gruesome discovery on Thursday, February 12 in a lay-by on the B818 Denny to Fintry road.
It was later discovered that six of the hens had been held down and stamped on, crushing their ribs. The necks of the other birds were broken.
Inspector Louise Seddon said: “Due to the two different methods of killing, this indicates two people might have been involved.
“At the bottom of the dustbin, there was loose chicken feed.
“These hens could have been rehomed and it’s tragic they were killed needlessly.
“There are organisations which can help owners no longer able to care for their animals.
“The hens stamped on would have suffered immensely and we are very keen to identify those responsible for this cruel act.”
Anyone with information is being urged to contact the Scottish SPCA animal help line on 03000 999 999.
