Twin Silkie embryos, but I do not see an air sac at day 12, should I see one by now?

    I was so surprised at there being two, it took a friend to point out she did not see an air sac. There is some clear yolk area around the chicks but I do not see an air sac at the large end. Should there be one on a silkie by day 12?

    The bottom looks clear but it does not look like the other air sacs on eggs I have hatched.

    Day 13, can barely see anything but shadows moving and the air sack is becoming more visible now.

    with all the handling the hatch might run a little long- what are your temps at now?

    I wish you would just have one thread on this...I don't know which one to follow.

    I have kept the temp at 99.5 throughout, I just lowered the humidity to 20 to 30 percent to try and discourage moisture gain in the egg. Tomorrow I am going back up to 40-50%, then on Saturday 65% with temp lowered to 98 degrees, then hatch on Sunday. As above I am going to be staying on the original thread. Thanks for any help.
