Winterizing the chicken house

we woke up the other morning and the watering unit in the chicken house was frozen solid. We looked around the farm for supplies that are laying around not in use and came up with a solution. We placed insulation in between each 2x4 and then sealed it with the peach colored panel. I think the peach color adds a little softer tone and brightens up the room a little.
Then the last thing we did was build three walls that surround the mobile. the front is still exposed and the roof has a little hole in it too. I have been monitoring the temp outside and seeing what days the water freezes. So far if it is about 10-15 degrees the water freezes. Thats a huge improvement on temperature. Every two days we take the panels off and spread mulch on the manure. This takes care of the smell and is starting a compost. once the compost heats up then the chickens will be alright for the rest of the winter.
