with numbers before they are placed in the incubator 

 for hatching. On the eighteenth day of incubation, the 

 numbered eggs are transferred from the regular egg tray 

 into the special tray. When hatched in this tray, the 

 chicks cannot get out of it. After they have been marked, 

 the chicks may be placed in a brooder with other chicks 

 with no danger of their identity becoming lost. Separated 

 trays can be used in any incubator. Partitions can be 

 made of tin or wood, and they can be placed in the egg 

 trays to separate the eggs as well as the chicks when 

 they are hatched. When they are used, the unmarked 

 chicks must not be allowed to drop into the nursery; if 

 this is permitted, their identity will be lost. 



To keep a correct record of chicks hatched by hens, 

 each hen should have eggs from only one hen given her 

 for hatching.

The toe-marking system is satisfactory for a small

 marking must be adopted. Bands of some kind for
