Has/does anyone use Tanks (Fish Tanks/Aquariums.. without the water! ) as a brooder? I had used totes up until we got 6 Muscovy ducklings but then wanted to try out a tank by using our 90gallon that we no longer use for anything else. It holds heat better than the tubs, IMO. We also have the new chickees in a large tank and they are staying warm, well, too. I also like it because we can use the screen lids and it keeps our dogs out and the chicks in, lol! Is there any reason that we -shouldn't- use a tank?
