Hi i live in northern ontario. I decided this past spring to convert my 6x6 shed into a chicken coop and raise a few chicks which ended up being 5 red sex links. So i ended up insulating my shed including ceiling and floor somewhat. I also put in 2 10x10 inch vents up as high as possibl. Up here in northern ontario, it can go as low as -35c from january to march. My questions are, Do I run a heat lamp How will they sand bath? Do i put a box of sand in the coop which in turn will take up needed space? Will they use the shavings instead for bathing? Any ideas how to stop the water from freezing? Ive seen the old light bulb in a center block trick and then set the watering containter on top. Any other good ideas. How about egg laying. The eggs will freeze. Do i try and slow down their laying by just giving them the natural light which will only be about 7 hours at best. Any advise would be appreciated.
