The first time I used my incubator, I had a complete failure (problem was with the eggs, not the incubator). This time I had five eggs hatch out of six.
When I got home from work there was one chick hatched and another two hatched shortly after. (I think the second two waited for me to get home so I could watch them.)
Then another one pipped. You can see the little egg tooth peeping out.
Then it zipped it’s way around the egg.
Then it pushed on the shell to make enough room to get out.
Exhausted and time for a sleep. After all, the pip did start at 7pm and the chick greeted us at 1:30am. Ah, hrrm, yes, well I did sit up watching the whole time. It was my first hatch after all. One of the previous chicks pipped, zipped and greeted us all within 20 minutes. These are Speckled Sussex chicks.
