Day 13

8 days to go!

I checked in on the eggs this evening, and it looks like the one i wasnt sure about has definitely stopped growing. So we are down to 4 :(

I couldnt get good pics because at this stage the egg is almost completely dark as the chick is starting to take up the majority of the egg. There is a light spot toward the fat end of the egg, which is the air sac. At around day 20, the chick will break through its membrane with its beak and breath for the first time from the air in the air sac, which will stimulate hatching, so it important that this sac is developing well. If it is too small, it could be because the incubators humidity is too high.
