closely followed. Since profit depends upon the amount and dura- 
tion of egg production, it is very essential that the poultryman 
keep in close touch with this branch of his work. In order to do 
this with the least amount of labor, the practice should be to post 
in every laying pen a so-called egg record (see page 455) which 
can be filled out daily with little labor and from which at the end 
of each month totals can be easily obtained. 
A careful study of such records over a period of years will 
enable the poultryman to know his flock better and to manage 
them more economically. 
Nest Eggs.—China eggs should be used in the nests, simply for 
the reason that they induce the birds to lay continuously in the 
same place. If it were not for their presence the birds would, 
after all the eggs had for a few times been removed, seek a new 
place to lay, usually the floor; this would result in cracked or broken 
eggs, many being entirely lost. China eggs are good to use in con- 
nection with trap nests, where it is necessary to keep the birds 
from laying on the floor. 
Egg Eating.—The habit or vice of egg eating usually results 
from the birds getting a taste of a fresh egg when one has been 
cracked or broken. It is a habit difficult to break when once 
established. The following conditions will tend to prevent their 
acquiring the habit and, possibly, to suppress the vice: Darkened 
nests; large roomy nests; frequent removal of eggs; the immediate 
removal of any broken shells or egg contents. 
Patented nests are advertised which allow the egg to roll down 
out of reach of the bird, but they are usually undesirable.
