This is a 5 tier breeder cage complete system for Quail. It has 15 compartments which enable you to manage your breeding sets closely to see which birds are producing or not. We recommend a max of 6 birds per compartment which would be 90 birds total possible. This system sells for $650 on their website but it costs almost $700 in shipping plus you have to assemble it once you get it here. Asking $600. OBO
