Pet Auto Doors is a division of our family owned manufacturing company (Bird In Hand Pet Structures) which was founded in 2007 on a farm in Lancaster County, Pennsylvania. Bird in Hand Pet Structures is an Amish run manufacturing company that builds chicken coops, dog kennels, and automatic chicken doors. Because of our experience with chicken coops, we understand the need and importance for an automatic chicken coop door that offers the proper options to make our lives easier. We believe that we have created the best chicken coop auto door on the market.
