Hey All!! So I'm finalizing my coop ideas(you guys are awesome and generous...) but I'm wondering about what is "extreme" weather? I grew up in Fla, so this whole white winter thing is still new for me. Below 70 is freezing as far as many of my neighbors were concerned... The area I live in now can get to be above 100 in summer, but very white in winter... and it's WINDY. Is there anything in particular ya'll can think of I need to incorporate to keep my chickies happy? I want an open plan, with one wall as a wind guard. I was thinking or using a "hurricane shutter" type of panel for winter. How does one ventilate without freezing the girls?
