Re: [CHICKENS-101] Eggs - Fertile last

 

Incubating eggs needs to be more precise than that. Egg temperature
needs to stay right around 99.5, but 105 will kill them. The difference
between 99.5 and 105 is not something that is easy to maintain without
the instincts of a broody hen or a good thermostat.

If you were to check it every five minutes, you might be able to
incubate with a damp towel and a heat lamp with a good thermometer, but
like the broody hen, that would need to be your 24x7 job for three
weeks.

I have learned of an inexpensive solid state temperature sensor which is
accurate to 0.1 degrees and I intend to build my own digital controls
for my little giant incubators. The little knob is hardly precise, and
takes a while to get set right. Programming 99.5 for the circulated
incubator and 102 for the still air would be much more accurate. (In
the still air incubator, air temperature will stratify with the highest
temperature at the top, hence the "higher" measured temperature for it.)
