It looks like wooden pallets will be how we at least frame up the coop. Since we have 25 chicks coming we are needing a larger building and the cost is growing faster than our budget. We have a source for free and nearly free pallets in good condition. For those who made coops with wooden pallets, I would love advice, warnings, hints, and so on. Doing a roof has me overwhelmed. I need at least a bit of an angle for rain and such to roll off. (Did I meantion I am a new builder too? ) We will cover the exterior with leftover wooden siding from a friend and will buy pressure treated wood for the foundation. The finished size needs to be at least 10x10, but I am aiming for 12x12 so I have storage room as well. Thanks so much!
