My family drinks a ton of milk. At least 5 gallons every week. What I'm wondering is... If I fill the empty milk jugs with water and put them inside my chicken house, along the tarp which divides the building, would they provide additional insulation? The water itself will freeze but would a frozen jug of water make it warmer, colder or have no effect? The jugs would be on the mostly empty half of the building, not the chicken half. Eskimos built houses out of ice and stayed very warm, so why not chickens? OTHO, ice is cold and tends to make the stuff around it cold. I realize there are better insulators, but I'm trying to use what we have on hand. Thanks for any input!!!
