filled with pus, scabs forming over them. It is said that 
a cure may be effected by thoroughly washing the sores 
with carbolic soap suds and applying carbolated vaseline 
afterward. 
CONTAMINATION.—A great many breeders think 
that if a hen runs with a male bird of another breed her 
chicks ever after will shows signs of contamination, from 
copulation with the bird of a strange breed. There is no 
ground for this belief. Sometimes when a hen is not lay- 
ing the effects of a copulation made a long time before 
will be observable in the first eggs she lays, but 1t is 
perfectly safe to say that a laying hen will not show any 
effects of copulation after ten days have passed from the 
time it occurred. The writer has had many breeds of 
pure-bred hens and cocks running together out of the 
hatching season, and he has never noted a single instance 
of contamination arising from this miscellaneous inter- 
course. 
COOKING FEED.—As a rule it does not pay to cook 
feeds. Most feeds give better results fed raw. Potatoes 
are probably better cooked on account of their starchy 
nature, and when liver or lights are fed they should be 
cooked to kill any possible disease germs that may be in 
them. 
COPULATION OF TURKEYS.—It is generally 
agreed that one service by a tom turkey is sufficient to 
fertilize all the eggs in one clutch or “laying” of a turkey 
hen. Instances are on record where one service has fer- 
tilized all the eggs for the whole season. A hen turkey 
will lay three clutches if prevented from sitting when she 
becomes broody.
