We purchased some eggs and chicks from a local small breeder last summer and she strongly suggested we get NPIP certified. We can't figure out how often we would have to be inspected and if the fee is annual or one time. Can anyone give us advice on if this is worth the cost and trouble to get. We only sell a few chickens a year but my husband might want to try and do more when we retire in a few years. Thank you for any insight!
