You can spend a lot of money for an elaborate set-up, but quite honestly, half the fun is being creative with the resources you have on hand.
There’s no need for fancy, chickens are very docile and non-destructive. Whatever you can provide that will protect them from predators is sufficient. Their nesting area needn’t be large, they actually prefer tight quarters. I made the mistake of giving every bird her own nest box when I first started raising poultry. However, one box for every two to three birds is definitely their preference. This nest box pictured below will easily accommodate four birds.
Store bought nest boxes are certainly pretty, but they are also expensive. Check the garage, or a flea market for something else that might be suitable. Apple crates work nicely for example. Or visit a Home Depot, they sell scrap wood in the lumber dept. for as little as fifty cents a board, what a bargain! Have your measurements ready because the first two cuts are free!
Here in Arizona it’s time to start a flock, the weather is perfect for chicks by mid October. In other parts of the country it’s time to research, plan, and prepare for the spring flock. Have fun in your adventure!
