Hi BYC, my parents recently got 5 chicks (about 2-3 weeks old now) so I wanted to build a coop for them while I am home for the summer. I was wondering about how big a coop and how big a run 5 full grown chickens would require? Also, if anybody lives in really hot areas (southern California or Arizona) do you guys have any suggestions for keeping them cool during the summer months? Any particular building material that would be useful for insulation and what not. I hope to hear from all you knowledgeable people soon! Thanks!
