Treatment. — Remove those possible — one louse may kill 
a chick — and smear the top of the head with a little pure 
lard. 
7. Sore Head. 
This is known among many poultry men by the name 
of chicken pox. 
Causes. — The principal cause is exposure to damp, cold 
rains and cold winds. It frequently follows such weakening 
diseases as roup or cholera. 
Symptoms. — It makes its appearance on the wattles, 
comb, earlobes and about the eyes in the form of warty-like 
projections. Some of these are not larger than a pinhead, 
while others become as large as the end of the finger. 
Treatment. — Remedy defects in feeding and care by en- 
deavoring to ascertain the cause and removing it. This 
prevents a recurrence of the disease. Apply the white 
lotion with a feather to the affected parts.
