In preparation for the hot summer days of July and August we tested and changed the filters on the misting system of each of our five mobile chicken houses. Each one hooks up to an irrigation valve and it is turned on once the temperature tops 95 F. The misters are set to cover the roof and out from the house, it is a sight to see when working. It reduces the temperature in and around the house by 10+ F.
The shade cloth is also deployed, so with the two heat protecting measure we have found that the stress on the girls is much reduced. The best way to gauge stress is how many eggs they lay, if the the number does not drop on a hot day they we are doing our job right.
