We put the 14 eggs in the incubator on 7th May 2013. I’m not sure how many had been fertilised but we should be able to see after 7 days.
The incubator has a rotating mechanism so it is not necessary to turn the eggs manually.
Every two days, we need to put some more water into the tray beneath so as to maintain the humidity level necessary for the eggs to hatch.
Last night, we put more water in and I took a couple of eggs out to candle them.
It was really exciting to see blood vessels developing inside some of the eggs and you could clearly see the outline of a minute chick.
I’m going to leave them for another 4 days and look again so that I can get rid of any that aren’t fertilised.
Apparently, it is easier to look at white eggs than brown ones and as the days went by, all I could see was some blood vessels and the air sac getting bigger. I couldn’t see any signs of life as some people on Internet were able to.
UPDATE 18th May 2013 (11th day)
When I looked at the eggs after 8 days it is not clear whether they are alive or not. I was expecting to see a heart beating but all I saw was a dark shadow and a larger air pocket at one end. I’ve no idea whether any will hatch or not, but here’s hoping.
Anyway, here is what I have learned so far about hatching and incubating eggs:
1. The eggs take 21 days to hatch
2. The ideal temperature for the incubator is 37.5ºC
On the 18th day, Saturday 25th May 2013, I took the incubator off the rocking cradle. For the last three days of their incubation, the eggs will not be moved. The separators of the incubator are also removed. It is also necessary to increase the humidity level just before they hatch.
On Sunday evening, one of the eggs had a hole in it and chirping could be heard. Throughout the next day the chick broke through and emerged:
