I am pretty new to chickens and bought a pre-made Precision Pet Extreme Hen House Chicken Coop to start my new flock. I live in a place with hot sommers and cold winters. It usually get to 10-30 degrees at night in the winter. I was wondering what I needed to do to get the girls ready for winter. I have 3 chickens and all of them are pretty cold hardy breeds. I'm worried about drafts. The coop isn't insilated aand has a opened door. There is also another door on it for access fom the outside that i was thinking about seeling up. I was also planning on enclosing the run area with plastic sheets. The chickens get out 2-3 hous a day. I think the coop is too small for a heat lamp. I was thinking about getting one of those heated floor mats but then we have to figure out some sort of extension cord setup. I aslo read that some people use snuggle safe microwaveable heat pads. That would sure be simpler. If i had another heat source then i would just have a small light to keep up egg production. Does anyone have any recomendations? I'll get some pictures of the coop later.
