At the beginning of March we started a flock with four (month and a half old) pullets. We've got to rehome a cockerel which makes room for another pullet (or two). I know that there must be a quarantine when adding new birds but is there any plus or minus to getting birds about the same age from a hatchery (mail order), a feed store or a local breeder? I've read that they should be kept at separate ends of the yard anywhere from two weeks to months. Thanks!
