9 Where a producer, dealer or hatchery operator markets broiler hatching eggs or chicks produced in a non-signatory province in interprovincial trade into a signatory province in excess of that producer’s, dealer’s or hatchery operator’s orderly marketing quota for that signatory province for a year, the Agency shall reduce, in such manner and to such extent as are necessary for the orderly marketing of broiler hatching eggs and chicks, that producer’s, dealer’s or hatchery operator’s orderly marketing quota for that signatory province for the following year.
