We are getting our first batch of chicks this month and didn't want them to be in our house if we could help it. We are building a chicken coop inside a lean-to and I wanted to know if I could insulate it with rigid insulation along the inside walls to keep the temperature at a good level. I want to keep it safe and am thinking the chicks would pick at it so we would need to cover it somehow. But, if we could make it safe, would it be an option to help keep them warm enough (we would have a heat lamp too)? We live in north Alabama and the temps this time of year average in the mid 60's/day and low 40's/night.
