We are looking for the cheapest possible way to start with chickens for eggs (10 Barred Rocks hens is the plan). We have a split basement, one side accessible from the house and the other only accessible from outside. We were thinking of turning the outside access basement to a coop area. It is about 10' x 15', and has a few small vents, but thinking we could add some larger ones to the door and sides (the top of the basement is slightly above ground). It has electricity, stays a comfortable temp, and it would be very secure from predators. We are planning on doing the deep litter method, which from my understanding has little to no smell. We then would have a run attached to the door, so they would have a decent amount of outdoor space during the day. Is this a reasonable plan or is there something I am missing that makes this a horrible idea?
