A fire at a two-story chicken house in Lititz, Penn., killed about 37,000 chickens that were being raised for poultry company Bell & Evans. An electrical malfunction in the chicken house is believed to have caused the chicken farm fire on April 29.

The building, which was lost in the fire, is owned by Nathan and Veronica Myer, the Associated Press reported.

Established in the 1890s, Bell & Evans specializes in antibiotic-free poultry.

The Bell & Evans fire marks the second North American poultry house fire in less than a week’s time. On April 26, a chicken breeder barn operated by Atlantic Poultry in Waterville, Nova Scotia, was badly damaged by a fire, which killed at least 5,500 chickens.
