103 Degrees Maintained
The temperature at which the incubators are carried for the first week is a matter of wide difference of opinion. In many cases 102 degrees is the maximum temperature for the first seven days, after which 103 is maintained as closely as possible during the remaining period of incubation. In operating the incubators on The Corning Egg Farm it has been found (and this is particularly true of early hatches) that, if the eggs are not brought up to 103 degrees for the first week, a retarded hatch is the result. A hatch which drags over its time usually means a lot of weaklings. It is our practice, therefore, to bring the eggs up to 103 degrees as soon as possible after setting them, and to continue this temperature as nearly as possible.
