Last year when I had the ducks I just did 2x2's with chicken wire. So decided this year just to put together something with the stuff I had on hand. Decided to make a brooder cabinet out of an old TV stand that I was going to throw out anyway.. I cut out a rectangle on the top placed hardware cloth for the bottom. I then built a cabinet out of 2x3's that was screwed directly to the stand.Not really big but I'm only doing hobby hatches for me so big enough..
I do have to lower the lamp though only running about 85 degrees right now.. Hope to be putting some chicks in hopefully a week from today..
