Verne E. Davison. National Waltonian, November, 1934. Article field in 
Prairie Chicken folder. 
"The hen (prairie chicken) lays her clutch of eggs, sets, hatches and

rears her brood with no companionship of the cocks, no protection except
her 
own smart maneuvers with what nature has afforded in shrub growth. Old birds

banded in 1932 are still living an raising young. In 1933, the banding 
records showed a ratio of 140 cocks to 100 hens (only the young birds being

considered). From a series of 412 young birds, the 1934 records show 146
cocks 
to 100 hens."
