Forget the coops for a minute, what about your living quarters?? It's 96 outside right now, and 81 in my house. We don't have the a/c on and I don't intend to turn it on unless we absolutely have to. I'm a stay-at-home-mom with a 2 year old. We're doing just fine! Although some of my friends think we're nuts. But they don't have to pay our electric bill
Here's what I'm doing:
During the day -
Close all windows
Close all blinds
Ceiling fans on medium or high
Floor fan sitting on the table with a frozen bowl of water in front of it
Cool rinse offs in the shower
Use ice in drinks
Don't use oven
At night -
Open windows
Put floor fan in front of the bathroom window to push cooler air down the hall
Keep ceiling fans on
Re-freeze water for tomorrow
Is there anything I haven't listed that you do?
