268 MANAGEMENT OF LAYING STOCK 
the color of egg (white or brown) demanded by that particular 
market, and then aim to produce that for which the highest price 
is paid. The stock selected should be constitutionally vigorous, 
and well bred for several preceding generations. If possible, they 
should be from a heavy producing strain, as the offspring of such 
are much more apt to be good producers (Figs. 135 and 136). 
Suitable Environment.—The laying stock, if economical pro- 
duction is to be assured, should be given congenial surroundings 
and an environment conducive to good health,—hence, to increased

egg production. Environment depends upon the size and style 
of house and the care of house and yards. Good care is important 
in the management of laying flocks. 
Proper feeding of laying birds at different seasons should be 
studied, and proper changes made to meet the changing conditions 
of season, weather, and age of the birds. The cost of feed should 
be kept as low as possible, and yet it must supply the nutrients 
required and in the forms most conducive to health and production. 
Care in Marketing.—Profit from good production does not 
depend alone upon a large yield of eggs; but, if the best prices 
and profits are to be realized, the eggs must be marketed in a 
manner, and at markets, which will insure the highest revenue.
