Our Started Pullets are 5-6 weeks old and have already been vaccinated for Mareks. A minimum order of 4 is required. You can choose to order 4 of one breed, or you can choose to get 1 of four different breeds or any combination of 4 or more that best suits you. All pullets are shipped USPS Priority Express and must be shipped separately from day-old chicks. Started Pullets are shipped with feed and solid H20 (gro-gel) to guarantee live arrival.
