The killings were done under the surveillance of a high powered committee formed by Directorate of Uttar Pradesh Animal Husbandry department to check the spread of dangerous viruses of the killer disease, Bazar Shukul livestock officer Dr Saket Yadav said.
Yadav said that the campaign may continue for two months.
District Magistrate of Amethi Jagat Raj Tripathi has asked the people not to worry as administration is vigilant on this issue.
This was followed a warning by an expert team that confirmed a "highly pathogenic avian influenza" outbreak in Amethi, where 350 birds, chicken and ducks died of a mystery disease on March 6-7. The incident occurred in the villages of Chandgarh and Sare Ka Purwa.
