See? Now you have plenty of room to make it like Mrs. AK's!! Have you seen hers? It is beautiful!! Could you imagine the possibilities? You can be your own hatchery!! (probably egg supplier would be more accurate, but you get the idea!) You could use it as a brooder, and when there is extra room, or when you get a lot of breeders, use part of it as breeder cells! Make the cages 2&1/2 feet deep, bottom cage for bigger/older birds-4&1/2 foot high, top cage only about 2 or 2&1/2 feet, so you can put the windows above, and not worry about any escapes. There could be a 3 feet wide walkway, and the bigger cages could be 4 feet wide. Ok, so that's 12 4' wide by 2&1/2 feet deep by 4 &1/2 feet high cages for bigger birds or breeder pair/trio, plus 8-2 feet wide by 2&1/2 feet deep by 2&1/2 feet high! Presto! Instant egg factory!! Put some tilting nest boxes on the front of the cages, and all you have to do is walk down the aisle and pick them up!! You could even get some QUAIL!!!
