Hi Egg Incubatorors !
We researched before we started incubating and I took the advice of a science teacher that hatches out eggs in their classes every year.
She recommended to hatch at a little higher temp. They recommend this because the incubator is being opened a lot to turn the eggs three times a day and take out chickies. (instead of one that has an egg turner and the incubator is only opened to take chickies out)
The thermometer recommends 99.5 degrees Fahrenheit.
We hatched ours at 102 degrees Fahrenheit and the chickies usually do hatch a day or two earlier. Which is nice, because then when the date written arrives, we pitch the egg. Also, you know there is only an expected 75% hatch rate, which was about what we saw. (for every 12 eggs, only 3 will not hatch)
I'd have to ask my son about the percentages for each breed. This should be interesting. We bred 5 different breeds and hatched out 111 eggs. On our website you can get the breakdown of how many per breed.
Sometime near the end of egg incubatation, I let him take over. He of course wanted to lower the temperature because he felt that was the more proper temperature. Whatever, he's taking care of them.
I know the Marans and the golden sebrights and the bb red OEG were the last breeds to be hatched.
I'm pretty sure with our Ameraucanas and Silkies, we got pretty much half. With the Marans, I know we only had 3 hens for the black ones and 1 or 2 for the blue.
I'll have my son work up a list and post it.
Give me a few days. He's returning from his trip late tonight. Will post soon.
Good luck !
Just wanted to tell you that 102 is still OK to hatch (cheapo thermometer that lays on top of the eggs). Only 2 or 3 died in the shell because they couldn't get out (too weak, should have helped them out).
The others were just not fertilized (he broke open the bad eggs that didn't hatch in the compost pile and there was just smelly yuck in there).
