Sorry if I am derailing this thread, but I gotta ask ----
@cavemanrich, why in the world are your chickens in the garage for the winter?

You are not derailing anything,,,,, But every good answer,,, deserves a good question

All my girls are pets. I have hens only.
I have Serama chickens and a 2 Polish chickens plus 3 other pet chickens. The Serama, are not cold hardy. The Polish have large Hairdoos, that mop up the water when they drink. Their heads would be frozen solid in winter if they were in coop, and outdoor run

. The Seramas would be,,,,, well Freeze-dried

Inside my garage I have a LARGE loft. that I also used to house pigeon in before.
I didn't measure, but estimate area to be about 60 square feet.
There is hay in portions of loft, Sand in portion of loft I use for dining area. Water is in 3 separate heated bowls. Lights are on a timer allotting 12 hours of light.
During extreme cold periods, I heat garage to just above freezing.
I don't have to worry about letting chickens out in morning, and locking up in evening. I do check water and food daily. Chicken don't seem to mind being there at all. Plenty of interesting thing for them to scratch and do all day.
Inside garage I also provide access to my feral population seen in Avatar. Separate food and water. There is small cat port door for them ground level of course.
