Question about the shelf liner in incubator

    When exactly do you put the shelf liner in the incubator? I have the shelf liner but didn't know if I should put it in on day 18, or sooner.
    I have 7 eggs in the incubator, it is day 10, we candled them on Day 7 and they were all growing. The eggs are from my hens, which are just hens from the neighbor down the road. Yes......... I also have a rooster [​IMG] They are nothing special, but they are good layers, every day I get 3 eggs from 3 hens.

    By the way, my temps have been holding at 100 degrees F and I finally found a water wriggler, and it is holding just a couple tenths lower than the thermometer. The humidity is holding at 49 - 50% Are these numbers okay?

    Thanks so much for all the help. I have learned a lot on this board.
    If I think of anything else, I will be sure to post it. I generally learn from reading what has already been posted.

    Merry Christmas,

    Good for you!! Your numbers look good to me, but then I killed my whole last batch so I wouldn't trust me. [​IMG] However, if you have condensation on your glass, your hygrometer might be off. Mine was off by 13% and I didn't know it [​IMG] Are your eggs in a turner? you don't need to put the shelf liner in until they are ready to hatch, but I don't think it would hurt either way.

    Hey, Skeeter! Your numbers are good for a circulated air bator. Still air needs to be about 101.5-102.
    I just put the shelf liner on the wire before I ever start incubating. Then it takes less time to get the hatching part set up on Day 18. Since you didn't, just cut a piece to fit beforehand and pop it in on Day 18 before you stop turning the eggs.

    I was just wondering; why does the temperature in a still-air incubator need to be 1 to 1.5 degrees higher than in a circulating-air incubator?

    That temp is at the top of the eggs and since the temps in a still air situation run hotter at the top of the bator, then the temps below, being slightly cooler, average out. A fan keeps the temps much more even throughout, so no need to have them hotter at the top of the eggs.

    Thank you for the encouragement! And the explanations of the temps. I will add the shelf liner on day 18. I forgot to mention that we have the still air incubator and we are turning the eggs ourselves. It has really been fun, I even get up in the middle of the night and check on them. I call it a "welfare check" We turn them 5 times a day.

    Thanks for answering my post.
