I need help from those who have converted their Little Tikes playhouses into chicken coops. I've researched as much as I could, but I'm not seeing straight answers anywhere. I live in TN and although winters are relatively mild, the temps do dip to negative degrees. I am loving the look of this Little Tikes Storybook Cottage playhouse and I'm hoping to buy and convert one into a chicken coop. The playhouse is quite pricey at over $400 (can't find used one locally), so I want to make sure before I purchase one. 1. If I patch the seams (other than top vent), will the plastic walls be adequate to keep chickens warm during winter? 2. Are these playhouses double walled where I could insulate further with spray foam? 3. Could a wall be cut to make a hole for chickens(entrance) without compromising the structure? 4. How do these plastic playhouses compare to wooden coops for insulation? Besides the look of the playhouse, I'm interested in the plastic playhouse because it may deter mite infestation and it may last longer than wooden coop. Thanks for your help!
