1929 Oflspring 



The males and females hatched in the two lines in 1929 may be roughly 

 grouped for surface plumage color as follows: 



Table 1. — Plumage Color. 



Light Line Dark Line 



Color 



Males Females Males Females 



Very light 2 2 



Light 24 20 11 



Medium 3 6 27 7 



Dark .' 4 14

Total 29 28 42 23 



The tendency of the males to appear in a lighter plumage class than their 



sisters is noticeable in the dark line, while there is no significant difference in 

 grouping of males and females in the light line. 



1930 Breeders 



Two hens were used as breeders in the light line in 1930. They were described 

 as follows: 



J1503 — Light orange, black-ticked hackle; light red surface; light under- 

 color and no smut. 



J2681 — Light orange, black-ticked hackle; medium light red surface color; 

 medium under-color, somewhat mottled but no smut. 



Male 1246 — Very light in color. 



Male 11206 — Very light surface color, very light under-color, no smut. 



In the dark line only one female was used as a breeder. She is described as 

 follows: 



J544^ — Orange, black-ticked hackle; dark red surface; medium under-color 

 and no smut. 



Male H3164- — Dark black-ticked hackle, medium dark red surface, medium 

 under-color, no smut. 



1930 Offspring 



Using the same grouping for color as was applied in 1929, the 1930 progeny 

 were classed as follows with respect to plumage color:

The number of offspring in the last generation is very small. This is due to 

 decreased egg production reducing the number of breeding females selected,
