well no electric up at my coops so not an option. I will have to say several of the girls in the layer house are pretty ancient and destined for the soup pot soon. All of my birds have been in a hard molt this year, including the pullet that hatched last Jan. so have been giving the benefit of the doubt for a bit. But their time is coming sooooon.....
I solved the no electric problem with mega amounts of 12 gauge extension cords. I think I had to run about 200-250 feet. Not the best option, but it has been working.
