So we are very new to chickens, like only 1 week. We have 2 RIR's and 2 Ameracaunas. They are almost a week old. My husband is trying to plan out the coop, but we are having a disagreement about whether there should be heat or insulation or some form of a fan to keep them cool. We live in Florida and our days can be very hot in the summer, but the coop will be placed in a shady spot. I know it does not snow or get super cold here but we have seen nights in the 30's in the winter. What does everyone suggest? We have about 4-5 weeks to figure it out and build it and I want to start on it as soon as possible. Thanks in advance.
