My family runs a small poultry and egg business. We currently have around 100 chickens in our flock, and we want to relocate and replace our old walk in with a new and more efficient coop. I really like the walk in chicken coop plans by Dave Malcolm on howtoplans.org. I was wondering if anyone has ever heard of Dave or his site? Also if there’s someone who’s built a chicken coop using their plans, please let me know if the plans are worth the money? Thanks so much
