mine cost 10 dollars and is very small footprint of 22 inchs by 43 inchs. Please excuse the mess we just finished building it and painting it. We. Only bought paint brushs and the top has hinges so it can be opened and cleaned :) I'm so glad to see other people useing their brains :).
Try a college around you. We use to buy LSUs chickens at the end of the spring section. It was to teach the vets how a laying place should run. They were all scared to death use to tiny cages but they lived out their life at our house and we never went without eggs
