I purchased an eight-foot stock tank at a flea market for $45. It had a couple of small holes in the bottom, making it useless as a water tank. Their loss, my gain. I installed some 2x4 across the top place in bedding, tie heat lamps to 2x4, cover with wire with two doors on top then cover that with a burlap tarp to keep the heat in since it is located in the barn. Can hold 50 chicks with ease.
