DIY chick brooder

I made this DIY brooder from some scrap wood and a pallet 3 years ago. Might be useful for someone. I have used it a lot for many hatches of chicks. It’s the size of a large pallet, I usually did about 30 chicks at a time in it. I have also included a picture of another pallet that’s available that used to be an extension to the brooder too, so I could do 60+ chicks. The brooder is pretty heavy so ideally bring a second person to help you get it in a truck.
