I have a 10 x 10 wire existing dog cage with an a frame roof and I want to add on living quarters for about four chickens. I live in the mountains and it gets in the 30s for about a month in the winter and it gets in the 90s about three months in the summer so I'm thinking I should have a insulated room using two by fours in plywood on the outside with some type of foam on the inside and then lined with maybe half inch plywood on the inside my question is is it best to have a raised floor for cleaning purposes or just a walk-in I can't seem to find the perfect coupe to fit my preferences and I was wondering if any of you had your preferences that you can share with me. And the ventilation on top is it necessary to have some type of fan that draws the air through in case there is no wind in the area
