Poultry farmers in Denmark were ordered by their government to keep flocks indoors after bird flu was found in wild birds across Europe.
The order does not include ducks, geese and wild birds.
European countries like Germany, Switzerland, Austria, Hungary, Poland, the Netherlands and Croatia have reported outbreaks of a severe strain of bird flu.
Danish authorities also ordered a farm to destroy more than 25,000 eggs imported from Germany that contained the highly pathogenic H5N8 virus.
Germany is also considering ordering its poultry farmers to keep their flocks indoors according to the country’s agriculture minister, Christian Schmidt.
The Netherlands earlier ordered its poultry farmers to keep their birds indoors and told them to boost the levels of hygiene and reduce visitors to a minimum.
