44 BRIGGS' SYSTEM OF 



In a room of 50 to 70 degrees begin airing your eggs 

 on fifth day and air each night, depending on tempera- 

 ture of room. 



A good airing for an hour or two on seventeenth day 

 will much improve your hatch in warm weather. 



Give plenty of air during hot weather. 



Good, fresh eggs hatch much better than those kept 

 two or three weeks. 



If you are hatching white eggs test them on fifth day, 

 and take out all clear eggs and dead germs. 



If you are incubating brown-shelled eggs leave them 

 in seven days, when you can test them nicely, taking out 

 all clear eggs and dead germs. 



They should be tested again at end of fifteenth day. 

 Remove all dead eggs and if you have not a good, fair- 

 sized shell you must give more ventilation, for you can- 

 not get a good hatch without a good-sized air cell. 



After you see your first pip do not open your ma- 

 chines again under any circumstances until your hatch is 

 practically through, say the morning of the twenty-first 

 day for Leghorns and end of twenty-first day for all 

 large breeds. 



Leave chicks in incubator fully twenty-four hours after 

 all are out. 



Just a word about buying an incubator, I have tried 

 nearly all the leading makes of incubators on the mar- 

 ket, and I firmly believe there is no machine made to 

 equal the latest Cyphers, made by the Cyphers Incubator 

 Co., of Buffalo, N. Y. It is far ahead of their old style 

 machine, and the increased depth to the egg chamber with 

 their nursery drawers makes it a first-class hatcher in 

 warm weather as well as cold. And I believe it to be as 

 near perfect as a machine can be built, and if you fail 

 to get a good hatch with it, as a rule, you will know the 

 fault lies either with yourself or the eggs. Now comes 

 the most difficult part of all, the business of raising the 

 chicks. Here is where they nearly all fail except those 

 using my system.
