I am a student that has been given an assignment of designing a chicken coop. I have not seen this anywhere, but it does not hurt to ask. Do chicken coops need insulation? I know that most of the coops are rather small but the assignment says I have a big lot and to maximize the amount of chickens I can hold in the coop. If the coop is about 10 feet by 10 feet, is that too big of a coop and would that required insulation if it is not too big? Thank you for your help.
