About Coop Designer
Size a chicken coop and run to your flock in 3D and get the material list
Coop Designer is a side project for people who keep backyard hens and want to build the coop themselves. You choose a hen house on legs, a walk-in coop, an A-frame or a chicken tractor, enter your flock and your yard, and the coop and run are framed in 3D from standard lumber. It checks space per hen, nest boxes, roosts, vents, hardware cloth and the apron against digging, each against a university extension guide, and lists every board, roll and screw to buy. The design lives in the share link; nothing is stored on a server. The designer is free. Pro is 19 USD once for a cut list with diagrams, the hardware cloth layout, a build plan PDF, add-ons and GLB or OBJ export.
