I am going to have to tell you about my brooder because I can't seem to find where to upload a picture!
We were not prepared to bring chicks home in May when we brought them home. So after a day in a box we finally had our brooder ready. My DH used the liner from the back of a pickup truck that he had out behind the shed. He built a frame and stapled chicken wire to the frame. He attached the frame to the top of the bedliner. At the end that was open he put 2x10's that he had out in the shed, stacked one on top of the other. He was finished and I looked at it and asked how we were going to get the chicks in it.....so, we cut a square out of the chicken wire and I had a wire tray that fit on top. He suspended a warming light on a tripod and we were in business. It was large but we bought 18 chicks and the next week added 11 more. All 29 made it and are living happily in the new coop and run. The brooder can be used again and it was all recycled materials. The coop and run also were recycled. The barn fell down next door and we used the tin from the roof of the barn after DH framed it out in used 2x4's. He had a door and frame out in the shed that he used for the door, however, we used a 7' chainlink gate at the door and leave the other open for now (and after killing a copperhead a few weeks ago) I now keep a window screen in the door to keep animals from getting through the gate. Then we cut a window out on the other side for a cross breeze and covered it with chicken wire....we will hinge the piece we cut out and make a cover for the window that we can close when the time comes that we need to. This coop is attached to a huge dog pen that used to be the home of a huge dog...years ago and is chain link. Once again we solved the problem of things crawling through the chain link by pushing some of the recycled tin into the ground around the entire pen.
So far we have been successful in keeping the bad guys out! Oh, and we made a frame to support wire and put a top on the entire dog pen aka chicken yard.
I think all the ideas are great that I looked at. It helps when you can use what you have lying around. Living out in the country it seems there are many things out there that can be reused.
Now, if they would just get old enough to lay me an egg or two....and we are still trying to decide who are the girls and who are the boys. I keep reading the posts about roos and hens and looking at the pictures. The day will come when we can actually tell. Some are already obvious....others are still a question. But for now we have a coop and pen full of happy chickens!!
