The crows have been sent to different laboratories across the country for finding the reason behind their deaths.
"As many as 14 dead crows have been recovered from the residence of the Chief Minister. The reason behind the deaths is not known", Regional Wildlife Warden V S Senthil Kumar told PTI.
However, he maintained that deaths can occur due to poisoning, electric shock or avian influenza.
The anti-viral spray was carried out in lawns and other areas around the CM's residence, Kumar added.
For testing and ascertaining the cause of deaths, the crows have been sent to Jalandhar's North Region Disease Diagnostic Laboratory, Bhopal Lab and SKUAST Jammu.
"Jalandhar lab has told us that it will take over a week to conduct test and give report", Kumar said.
