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.
