Since chickens grow like weeds, my husband made our 5 chicks a grow out brooder that they wouldn't outgrow so quickly. It is "L" shaped so it fits nicely in the corner of our sun porch. It is 7 ft tall and both levels are a 4ft x 4ft x 2 ft deep "L" shape. It has two levels that are both 3.5 ft tall and are connected by a "ramp". It has four doors that can open for easy cleaning and be locked securely. The top level acts as their coop..it has 2 roosts, and an automatic waterer and feeder. The flooring is vinyl for easy clean up, also. The bottom level acts as "run" space for them to play in..and they do. lol. They love it! They have more than enough space, and we love knowing that they're comfortable in there until we get their coop done!
