Where I live we have winters that can get to 20 below and summers that can get into the 100. I am a first time chick mom of 5 chicks all about 2 1/2 weeks old. I have a Cocko Maran, an Ester egger, 2 Mixed, and a White Crested Black Polish. I don't have a coop yet but I am thinking of getting a large 6.5 x10 chicken run and getting something like a dog house that I could do a bit of work on to make safe and comfy for my babies. Does anyone have any helpful hints or advice about what I should do to keep them cool in the summer and warm in the winter. Plus if you could tell me any common sense things that I might not know about would be great. Thanks a lot guys!
