Amid a bird flue scare, shops selling poultry meat in the national capital on Friday claimed they have recorded a 20-25 per cent dip in sales over the last few weeks. A Delhi government official on Friday said around 50 birds, mostly crows, have died in Dwarka, Mayur Vihar Phase-III and Hastsal in west Delhi in the last three to four days. According to Poultry Federation of India president Ramesh Khatri said, There has not been an outbreak of bird flu in broiler chicken anywhere in the country. Still, their prices have fallen at farm level by up to 50 per cent due to sentiments.
