I would say yes, the dog house could probably easily modified to house 4 hens comfortably as long as they able to free range during the day. Chickens need about 4 sq ft per bird if allowed to free range and a minimum of 10 sq ft if penned up all the time. With 4 birds during their peek laying you can expect an egg a day per bird, so a dozen every 3 days. At $2 a dozen you could pay for their food easily every month plus several for you, your family, and maybe even your neighbors if you like. If you have any more questions please ask I love me some chicken talk.
