im starting with 4 chicks this weekend. they will be in a rabbit cage inside the house until they're big enough (feathered?) to go outside in the tractor we're building. my question... what do i do with the boys? im sure at least one will be a boy and i dont want that.. i only want hens. but its not like i can return the boys to the feed store.... and since i want 3-4 total, how do i introduce new ones after i re-home the boys and buy more chicks? thanks!
