POULTRY BREEDING AND MANAGEMENT 



chicks. Rotten eggs should also be removed. If a number 

 of hens are set at one time, they may be doubled up after 

 testing; that is, if as many as a sitting are tested out, one 

 hen may be reset on fresh eggs. An egg-tester may be pur- 

 chased from a poultry supply house, or a small box may be 

 used in which an electric light globe may be put. A coal 

 oil lamp or candle may be used instead of an electric light 

 bulb. (See pages 353-354.) 



In one side of the box cut a hole about the size of an egg. 

 Testing is done in a dark room or at night by holding the 

 egg to the light at the hole in box. Eggs may be tested by 

 daylight by holding the egg at the end of a tube or funnel 

 and pointing it toward the light. "Where the incubator 



room is fairly dark the 

 eggs may be held at a 

 hole in the wall and 

 tested. "With two holes 

 a little smaller than an 

 egg, two eggs may be 

 held up at one time. 



In testing incubator 

 eggs the tray may be 

 taken outdoors in the 

 light and by using the 

 funnel looking down on 

 the eggs they may be 

 quickly and easily 

 tested. Another method 

 of testing without hand- 

 ling the eggs is to use a 

 flashlight under the tray 

 in a dark or moderately 

 dark room and looking 

 down on the eggs direct- 



DIVISION OF POULTRY LABOR 



Some of the poultry farmers at Peta- 

 luma, Cal., take the eggs to the hatchery 

 and pay the hatcher 3 or 4 cents apiece for 

 hatching the chicks. The photo shows part 

 of a hatch of 1,500 chicks at a Petaluma 

 hatchery, which are to be taken by another 

 party to raise.
