Double Mating. For extreme double mating, select the hens 

 that have produced the best exhibition males and mate them with 

 the best exhibition males that you have or that you can secure. 

 Toe-mark all the chicks from this mating and from them estab- 

 lish a cockerel breeding line; keep them separate and apart and 

 use them only for producing male birds for the exhibition. This 

 line should be as carefully separated as are the matings to pro- 

 duce cockerels in the Barred variety.
