Many people have an erroneous idea in regard to the time required for hatching. If the temperature has been carried at a correct point during the entire period the eggs will begin to pip on the afternoon of the 19th day, and the morning of the 20th day should find the youngsters coming out of the shells like Pop Corn over a hot fire if the eggs have been of proper strength, but on the morning of the 21st day the hatch should be completed. Generally speaking, chicks which hatch later than the 21st day are weak, and while they may come along for a time, when placed in the Brooder House they generally snuff out, and add to the list of mortalities. Set Incubators Toward Evening It is our belief that there is a best time in the twenty-four hours in which to set an incubator. As a rule, it requires about eight hours after the eggs have been placed in the machine for it to come up to temperature. Therefore, if the eggs go into the chamber late in the afternoon, and anything goes wrong with the regulator, the eggs cannot have been in a detrimental temperature for any great length of time before the operator is making his first morning round. We observe the temperature in the egg chamber three times a day as a rule, the first thing in the morning before the eggs are turned; at noon, or a sufficient number of hours after turning and cooling the eggs, allowing a sufficient time to elapse for coming up to temperature; and again late in the afternoon, before the final turning for the day. At these hours of observation any slight alteration of regulator, to meet changes noted in the temperature, is, of course made. The Hot Water, Coal-Heated, Incubator is a great step in advance, and these machines are now built in sizes from twelve hundred eggs up. With the old style lamp machine, people who were running a small plant did not need an Incubator Cellar, but the Insurance Companies would not allow the placing of an incubator in the cellar of a house without a special permit, and in many cases would not issue such a permit at all. The hot water machine will, of course, go into any cellar without vitiating the insurance, and, what is more, the machine itself is insurable, just as is any hot water plant in a house.
