    Hi,
    Another question, Sorry! [​IMG]

    When you first get eggs do you ever candle them to see if there is an air sack?

    If when you are candling them you cannot see an airsack, do what?

    We candled some, thought we saw bloodrings but have left in, they are not smelling or anything but we candled again and now I am not sure at all.....[​IMG]

    Alos if you candle them and they look more clear, when/should we get rid of?

    More porus shelled eggs, the ones that you can see the spotting of light thru, are they any good?

    We have some on day 7, can see some veins on some, others look clear with no air sacs.
    What to do?

    Thanks a million everyone!

    Ok, on day 7... you should be seeing an air sac in all the eggs, developing or not. Not being able to find it indicates your humidity is too high. I toss clears and rings on day 14 as long as they don't stink.

    I was going to give you the same answers as Silkie did...plus I have had porus eggs that have hatched out nice chicks before...some say not to incubate them but I've been sent them and always had good luck with them hatching....

    Thank you both, our humdity has been 40-50% temp 99-101, LG still air.
    Should the humidity be closer to 50?
    I seem to read different things everytime I find more information, humidity 40-50 then some places suggest 60-65, etc...
    Any thoughts?
    Are we doing this right?!?
    LOL!

    Also before you even put them in can you candle and what should you look for? anything to suggest they are fertile? what if you candle and can't see an airsack then?

    Thanks!!

    horsechick asked:
    When you first get eggs do you ever candle them to see if there is an air sack?

    Yes, I always candle and I even circle the air sac with a #2 pencil on the egg itself. I get some where air sac is on the wrong end. I am soon going to learn NOT to set these but for now, I set them in the turner, air sac UP.

    If when you are candling them you cannot see an airsack, do what?

    It is there somewhere. To be safe, if you don't see it, then store it small end down & set in turner the same way. Some eggs are not hatchable because they will have very tiny air bubbles under the shell.

    We candled some, thought we saw bloodrings but have left in, they are not smelling or anything but we candled again and now I am not sure at all.....

    Leave them alone if you are unsure.

    Alos if you candle them and they look more clear, when/should we get rid of?

    I wait ten days and if they still look clear, I get rid of them. Always crack open, look and confirm your findings.
    We have some on day 7, can see some veins on some, others look clear with no air sacs.
    What to do?

    If you can see very discernible differences in the live ones (with veins) and the clear ones at 7 days, then go ahead and discard the clear ones. Crack open the first one and confirm your belief.

    anything to suggest they are fertile?

    No. I wish there were a way.

    [humidity] Any thoughts?

    My best hatches have been when I am able to maintain my humidity through day 18 at about 55-60%. I have trouble with humidity sometimes running too high as I live in Alabama.

    Temperature is more important than humidity. Here are some eggs ad day 6. You can see about where the air sac is and how big it is. If you can't see any air sac, humidity is too high. You should be seeing air sac by now.

    Only way you can tell fertility before incubation is to crack eggs ...lol... no way to candle and tell that before hand ..by day 7 is when you start seeing veins if your new to candling and hatching and should know they are fertile..some old pros can candle and tell before then......my hatches at my house the humidity needs to run at 40 to 50% first 18 days...everyone has something different...the last 3 day for me I get clean hatches with 60 to 70%...

    now, to find the air sac, you should put the light right on the big end. If you dont, you wont see it.

    Thanks everyone!
    I wish I could get good enough photos to post and see what everyone thinks, maybe try it sometime.
    The Lg humidity seems to be staying at 40-45 mostly. I have tons of little sponges in there and all reservoirs filled, plus two littel cold medicine cups. one vent in one out. How can I help bring the humidity up a tad?
    Thanks!!![​IMG]
