Just talked to my brother in law... apparently I inherited this virus from my sister, who was down with it yesterday morning, didn't tell anybody, then went to my Mom's house and hung out.
She realizes NOW that it wasn't a good idea... apparently I can come across not-so-nice when not feeling good...
Anyway. I was doing some money calculations on the cost of building more coops... then had a bit of an epiphany. Yes, I live in the city. However, I have an already poured 8x10 concrete slab in my back yard... used to have one of those cutesy wooden kid playhouses on it (only know because my neighbor still has hers). However the mini house was already gone before I bought it, only the slab remains. So I called up my bro and asked him how much it cost them to put a shed in their back yard, he said that I need to figure out if the slab is thick enough to anchor the building to it, which would cross out the majority of the money he spent on his shed (the floor was expensive). So guess that means I get to dig a hole by the side of the slab and figure out how far down it goes.
Because of the dog issue, I'm figuring on building the shed and fencing around it. He suggested skylights for natural light, and some kind of continuous ventilation? Not sure what it was called, but he works as a foreman for an insulation company... they do guttering, fireplaces, insulation, vent installation, etc so he'd know what would be best. Said he'd have a rough estimate on wood cost minus flooring tomorrow. It might cost more in labor, but it'd be a darn sight better than more coops. Oh, and he has already figured out how we could split the interior of the shed to keep the layers on one side and the MFCs on the other and still have adequate air flow.
