Attempting hatching after a bad hatch

[alkitcat]

a few days ago I went through a pretty traumatic hatch where only 2 out of 6 eggs hatched the rest bled out after hitting a blood vessel, didn’t fully absorb and one I believe suffocated after being unable to pip externally. I have the two chicks in the brooder and once they’re old enough to be moved outside I’ve decided I’m going to try incubating a new batch again. Any tips and tricks would be wonderful, I have a thermometer and hygrometer on the way to more accurately be able to tell the temps and humidity as I’ve got a janoel12 incubator and someone told me the temperature can be a bit iffy. My one problem with the incubation process is I’m always compelled to candle them is there any way to avoid the temptation? Also I’m probably going to use shipped eggs as I’m again in a situation where I don’t have the mobility to go out and get any locally. I buy eggs from Durham hens..

make sure to have humidity at right temp, chickens eggs do need to be turned don't worry about it unless your incubator doesn't have a turner, have at right temperature, and keep them healthy

If you haven't read it already, this article by @Pyxis will help prepare you for your next attempt. It also has a section specifically about shipped eggs.

As far as the compulsion to candle goes, you really won't see much before day 5 so why not wait until day 7? And each time you take eggs out to candle, you run the risk of dropping them -that's enough to keep me to candling on just days 7 & 14 (and maybe right before lockdown if any are "iffy") for chicken eggs.

Best wishes for a good hatch!

The one hitting the blood vessels is an unavoidable accident. The two others can have to do with temp, humidity, turning and/or handling if they're shipped. Shipped eggs come with the risk of being handled badly in the mail, so keep that in mind if you choose that.

Depending on how your incubator is built, candling won't hurt. Momma hen leaves the nest once a day to eat in which the eggs get colder, so candling once a week won't mess up things. Just make sure the temp and humidity returns to normal after you put the lid back on. Actually, if you like candling, you can use the method of monitoring the air bubble to check for correct humidity while you're at it.

I hope your next incubation goes better. Good luck!
