This is a chick brooder that I made out of a truck bed liner and some 2x4's. I had 25 chicks divided into 2 different plastic storage bins, but they quickly out grew that. So I made this and now all my chicks are together and have plenty of room to grow! At night I cover it with a tarp to keep off the wind and it helps to hold in the heat. It seems to be working well, (so far)!
