It sounds neat! Any pictures?We converted an old shed into a bigger coop for our egg layers. Right now there are just the 16 (15 girls & 1 boy) in there but I plan to add more next year. The coop is about 8 x 11. It doesn’t look like it was built with any real plans except to be functional. No two stud spacing a were the same, nothing was exact but it works. We insulated the walls and built a big covered run. Nothing is picture perfect but it is functional and the chickens are warm & dry. They went from 15 feet of roosting space to over 20 feet of indoor roosting space with room for more. The run is 8 x 30 & is fully covered.
Our original coop is 11x5 or 6. Part is coop and the other part is covered run. It also has a larger attached non covered run. Right now it has just 2 Silkies and their Brahma friend. She has been with them since they hatched and has always lived with them so she thinks she is a Silkie too. They sleep in a big heap on the coop floor all cuddled up. LOL! We may add a few more friends for them next year too.
