The RSPCA is appealing for information after more than 100 chicks were dumped in the Cambridgeshire Fens.
Two large batches of chicks were left near Wisbech over a three-week period in March and April.
- 29th March - 26 chicks dumped along Franks Lane, Newton.
- 13th April - 81 chicks, and 60 dead ones, found at a rural location in North Road, Tydd St Mary.
The chicks are now being cared for at RSPCA Block Fen Animal Centre in Cambridgeshire.
RSPCA inspector Deborah Pert said: “It is very unusual to have such a large number of chicks abandoned.
"The RSPCA is very grateful to the members of the public who found the chicks and kept them safe until they called us to collect them.
"The chicks were found in and around some old tyres near the location.”
Inspector Justin Stubbs said: “We do believe these two incidents are linked, given the similar age of the dumped birds and the fact the locations are close to each other.
“Whoever dumped these birds had effectively left them to die, they had no access to nearby food or water or shelter from predators."
Anyone with information can contact the RSPCA inspector line in confidence on 0300 123 8018.
