the frozen water and my chickens just looking miserable. So last night on my way home I bought another 250 watt heat lamp and socket to add to the one all ready in the coop. This morning I was very happy to see that the water bowl didn't have a hint of ice. The heat lamps are not over the water either. I nailed them to the coop walls about five feet up on either side of the coop. It got down to 18 degrees last night so I was happy. NOW we will see what happens when the temps get to a low of zero tonight and only a high of 8 degrees tomorrow and minus 2 on Friday night. The coop is a 8 x 12 that is 8 feet high at it's peak and has 24 chickens and two caged ducks.
