I have had chickens for about 20 years now. We usually don't have a rooster, so every 2 or 3 years I get I new batch of chicks. I got chicks last year, and thanks to a persistent raccoon I'm getting chicks this year too. I have been using a large tote in the house to start them out for many years. It a total pain. I'm short, so it's difficult to reach, and care for the chicks. They also fill the water with the bedding immediately. I'm always fighting to lid, and the heat lamp.
I decided I wanted something more functional. I built a brooder. I'm not a carpenter, and there are lots of mistakes. I also used a lot of repurposed wood. I bought 6 fence pickets, hinges, screws, and some paint. Everything else was pallet wood, or wood given to me from no longer needed stuff. It cost me about $70.00. 30.00 for the pickets, 18.00 for the paint, and 10.00 for the bottom tray, and around 10 to 12 for the hinges and screws. I already have the hardware to cloth.
I'm quite pleased with it. It cost more than I wanted to spend, and took a lot longer to build then I thought. I think it's going to be so much more functional.
I bought a dog crate tray, and built it around the tray. I made a door to easily remove the tray to clean. I made a door in the front because I'm short and have a difficult time tending the chicks. There's a small elevated section on one end for the food and water in hopes of keeping them from filling with the bedding. That end also has a door for quick and easy food and water maintenance. The top is removable with 2 screws. ( if I end up needing to remove the top more than I think, I will put hinges on it). The legs are a very basic frame, and not attached. There's hardware cloth under the tray. when it's warm I can take the brooder outside, remove the tray a the chicks can play safely in the grass.
I don't have the chicks yet, so we will see, but I think it's going to be a lot nicer for them, and a lot easier for me.
