This is going to be interesting, our first run at incubating eggs. My husband and I are new to chickens and love them to death. Although we have 3 Golden Comet chicks coming later this week we wanted to get a "trial run" in at incubating eggs, with recently receiving my father's old little giant incubator we figured no time better than the present to see how it runs.

I have done a ton of researching and this is what I've come up with: my circulated air LG needs to be running at 99.5 with a humidity of about 35%. Candling at days 7, 14,and 18 will help determine the quality of the air cells of the eggs, and after day 18 I remove the turner and set the eggs on lock-down with a humidity of about 75% and that using a large wet sponge will help to maintain a higher humidity during this period. **If I am missing anything or are incorrect about any of this please, please, please tell me**

After a few long days of fighting with the incubator and the three different thermometers/hygrometers I have purchased (and since returned) and trying to get the old hens to lay I finally have enough eggs and a stable environment to set my eggs. So off we go....

As of 3:30 on 3/22/14 we have 10 eggs set with a hatch date of 4/12/14.

Question: I remember reading somewhere to keep both vents closed during the first 10 days then to open 1 air vent for the rest of the incubation period. Is this correct or will the CO2 build up end up harming my chicks to be??
 
Is it a still air incubator? If so there would be no problem with keeping both vents open, but when you need to raise the humidity during the last few days I would close one of them. Seems to me everything else you said is just fine.

The LG incubator is forced air would that change anything?
 
Then I would just keep one air vent open. If it is forced air then it keeps the air inside circulating but would still need some fresh air. I don't think it would hurt though to keep it closed for first week.
 
Great to hear :) hope it all goes well. Would love to see them after they hatch.
 
Subscribing. Sounds like you are doing everything right. I have a still air LG and haven't opened either vent. I probably will tomorrow or Tuesday when I have time to watch it and make sure the tells remain stable.
 
My hygrometer died on my last night and I have no idea what the humidity is in there but luckily they are next day shipping me a new one. Fingers crossed this one works
 
Quote: I'm not saying anyone is wrong or right in the advice you've received thus far, but for a difference of opinion.... I do not close the vents on my incubator at all, ever :-)

I believe having both vents open helps the incubator to regulate off the room humidity a little better, which works well for me in Oregon where the room the incubator is in is 40% (incubator @ 35% dry hatch). I think different people have different methods on day 1-18 venting, and either method works. But please make sure the vents are open when they start to hatch, it's important for the chicks to have oxygen once they start using their lugs (internal pip / day 19)

The room that the incubator is in is only like 30% humidity. However I do have one vent open now as my new digital hygrometer/thermometer has a probe that fits nicely into the vent hole. I do plan on having both vents open once we hit day 18 maybe even sooner haven't figured it all out yet, just playing it by ear as I go along
