My flock has grown to 18 chickens and I'm thinking I need to improve upon my existing coop. I'm fully prepared to pull down the entire thing and start fresh, but Im having a really hard time finding something appropriate for that many birds. Especially with winter coming (I'm in Charlotte NC area), I want to be sure they can all be cozy. Not opposed to plans for building or a kit. The ladies free range during the day, so it's really just to make sure they have a warm, draft free bed/roost at night and lovely nesting boxes for the yummy eggs. Any suggestions would be greatly welcome!
