On day 13 (of a total of 21) I noticed a half degree rise in temperature which was to be expected.  As chicks develop inside the eggs they begin to generate body heat, so you have to adjust the temperature in the incubator.  On day 14 the temperature shot up to 104 degrees, and I panicked!  Did my eggs have the flu or something?!  They seemed to be running a fever.  As soon as I noticed I turned the heat down and opened the incubator to cool it back to the correct 100 degree temperature.  It has left me nervous and a little over protective, so I'm checking the temperature several times a day now.  

After the egg fever, I decided to see what was going on inside the shells.  Using a special flashlight to see the interior of the eggs I took a peak.  The dozen blue/green shells showed nothing.  These fancy colored egg shells are simply impossible to see thru.  Of the 17 hybrid brown eggs 12 were mostly dark inside.  Chicks were clearing developing in those eggs.  The other five had nothing but yolk and white within.  I guess the rooster wasn't doing his job right on those hens.   

So the eggs-periment continues with a count down of 6 days.   The temperature looks good, and I'm  hoping the over heating didn't do too much damage.  I'll continue turning the eggs twice a day, and soon I'll open the air holes for when the chicks start to breath inside their ovoid homes.  I'll also have to add more water to raise the humidity and keep the chick-in-eggs from getting thirsty.  Day 20, Monday, will be the next milestone when the chicks start to peep from inside their shells.  If that happens we'll have chicks on Tuesday.  Keep your fingers crossed.  This could be a fiasco.
