I just bought and put together a chicken coop/run that was on Craig's List. Really nice. It's T-shaped with a 8x4 run and 5x6 half run and half coop. The 6 nest box are on the outside. It has 6" ceiling with a shingled roof. All treated lumber, heavy duty. It was less than a year old and hardly used. I bet the guy had at least $700 in material. I paid $150. I just ordered some more chickens that will be ready for pick up on April 13th. They'll be 5 weeks old and feathered up and ready for outdoors. I've got other chickens in different size cages. I was just wondering how many chickens you guys think could be in this new house. My new ones are all layers. SLW,Whites rocks,barred rocks Marans,Orpingtons. Thanks for any advice.
