The birdhouse was knocked to the ground & broke open during a severe storm.
I was horrified to find sharp staple ends piercing through into the interior of the house- probably 20-30 staples, so many that any bird inside would be at risk of injury.  Now I know why no birds used this house. It was a wasted purchase & potentially harmful to the birds I wanted to help.
Please consider pulling this house from those you sell.
