I'm not planning on getting seramas but I would just like to know, would they be okay where I live? We have a decent sized coop that we keep the door open during the summer so that the air will circulate, but have it closed in the winter. I live in NE Georgia so it gets really hot during the summer(around 100 degrees on hot days) but in the winter time it gets fairly cold(rarely getting into the teens but it does happen) so I was wondering would I need a heat source for the coop? It snows a couple times a year and I wanted to know if this would be a problem. What could I use to heat the coop? Here's a picture of it: Notice the door is open because it's so hot. Is this okay? I just thought it would be unbearable for the door to be closed and have no air to circulate when it's hot. Thanks!
