should keep; namely, an account that will 
show him the total production of eggs, the 
total consumption of scratch feed and mash, 
and the mortality. A record sheet such as 
is here suggested gives all the information as 
far as feeds are concerned, gives the poultry- 
man an opportunity to know at the end of 
each week just how many pounds of feed have 
been consumed, and discloses what the pro- 
portion of mash to scratch feed has been. 
After such records have been kept for a 
period of two to three years a poultryman 
can devise feeding formulas or proportions 
of mash and scratch which his own particular 
strain of hens needs under his own particular 
climatic conditions. 
Incubator and Brooder Records. In- 
cubator records should be kept which give 
the poultryman a knowledge as to the fer- 
tility of his eggs, the total number of dead in 
shell found in each hatch, and the total 
number of chicks hatched. Brooder records 
should also be kept which show the mortality 
of the chicks and the dates when they died. 
These should also furnish him information
