24 and 25 days Still Alive????????????????????????

[mmtruckauth]

Hey all here is a good one for you.

We are at day 24 and 25 on different eggs. We did the float test on them today and all of them floated but no movement. We put them all back in the incubator not knowing what to do with them. And low and behold we have three of them moving. So should we let them go or what. We have had some issues with the temp staying up where it needs to be all the time. We do have a still air incubator and were told to keep the temp at 99.5 degrees which from what I am understanding is a little low.

So how long should we give them. We have had 5 hatch and were out of town tell today but as of day 22 none of them had hatched. So of the 5 we have hatched they didn't come out tell day 23 or later.

Please advise us what you all think we should do
Thanks

In a still air incubator you need the temperature to be 101*F measured at the top of the eggs. Even 1*F under this can delay the hatch by 24 hours, as the embryos developed a bit slower than they should in cooler temperatures. They could still hatch, so give them another day or 2. Keep an eye on them and candle them to see if they pipped internally before doing the float test again, if you want to check viability. If you float test after they pipped internally you risk drowning the chicks. I found a good, safe method of checking over due eggs is tapping them. Hold the egg against your ear and listen, if you don't hear anything gently tap the egg with your fingernail. If there's a live chick in there it will respond by either pecking the shell, chirping, or moving.

How can you do that if you aren't supposed to open the incubater?
