Hello All! I'm getting started on my coop and was wondering about the door. I have a deck box that I will be using for the coop. It's 10sq/ft of floor and is intended for 3 banties. I like it for a few reasons: *it's plastic and easily cleaned *the doors and top lock *it won't scream 'chicken coop' in my suburban backyard (lot size only 30x100 ft, so neighbours are close) I'm just curious about the door. This website, at the bottom, shows what I'm attempting to do (mine with better vents). http://greenterrafirma.com/chicken-coop.html It looks like they use a catdoor for the chooks. Anyone have a catdoor? I have seen a bundle of them online that are 'lockable' but I'm just curious how sturdy they are and if this is a plausable idea? We are in a community close to farmland (can see cornfields from my bedroom window as far as the eye can see...) and want it to be secure from raccoons, weasels, ect. I'm thinking it would be easiest because the deckbox is double-layer resin with air between the two layers and it would be easier to install a catdoor rather than make a wood one that locks. I can get pet door at the pet store for about $15. Thoughts?
