It’s fully enclosed. Measures 42”L x 37.5”W x 26”H. It has a roosting bar for when they get a little older. Use a simple carabiner to lock it closed. We would line it with cardboard and then layer in wood shavings so it’s easy to clean. Will also include a chick heater, chick feeder, and chick grit. All you need is a carabiner if you want to lock it, and a waterer.
