Day 23 and only one chick...

[Guess what]

Hi!
I have been incubating 30 eggs due to hatch yesterday. I have read and reread everything I could get my hands on to make sure I do this right. I am using a hova bator incubator with a fan and automatic egg turner. On day 18 I took the egg turner out and put the eggs on lock down. Temps have been at 99-100 degrees the whole time. Humidity stayed at 50-55% the first 18 days and has been ranging 60-70 (mostly 65%) since they have been on lock down. We had one chick hatch on day 20 and have been waiting patiently since. I saw some movement of eggs rocking on day 20 but nothing since. We are ending day 22 now and worried the others will not hatch. Are there any adjustments I should be making? I will need to open the incubator to pull out the lone chick soon to get her into the brooder. Is there anything I should do other than wait?
Thank you!

You can pull the hatched chick out anytime. There is nothing you can do at this time. I would almost put money on the fact the rest will not make it and I would be as willing to go as far to say they drowned. Few people have success at 50-55% humidity for days 1-17 (even though the bators and older material recommend it) because it prevents the egg from loosing enough moisture.

If you think there's any possibility at any of them being viable at this point you can candle them. But I think the point of viability has passed.
