How many chickens can it house? I did note that the playhouse's interior dimensions are only about 3 1/2 feet square.
Now, if this really works well, that would indicate a market for similar structures, only optimized as chicken housing. (Without features like the doorbell which are not useful for the chickens, but with features like built-in nesting boxes and chicken sized pop doors. Or perhaps just bulit-in attachment points for nesting boxes and roosts.)
Also, a question about the aluminized bubble insulation. I was thinking of using it in the chicken tractor I am building for use here in Vermont. How has it lasted during the year since you installed it? Do the chickens leave it alone? I am thinking they could destroy it pretty fast if they decided to start pecking at it.
