We bought a small coop when we first started out with chickens a year ago. We are adding to our flock and want to create a bigger coop but not a huge one. This is what ours looks like just a general prefab one. We will have 4 chickens and want to make more room for them. Where do we start? We found we really would like to put a heat lamp in to keep them laying through the winter any suggestions? We would have to run an outdoor power cord in order to make that happen. Any suggestions would be appreciated. I have been checking out all the coops on the site they are great but a lot of them way too big for what we are wanting.
