Float test accurate?

[ourrune]

Hi guys! I had 7 eggs and 6 hatched, yesterday one that was growing a little slower, because my bad fan blew right on it so the temp wasnt right for him, he didnt hatch on hatch day, everyone else did day 21. So after everyone hatched, i turned humidity back down to normal so his air cell had a chance to grow because his was only at dayb14 size not day 18 or 21 for that matter. We went out and i realized i left the lid to the glass on and it probably got way too hot in there for him so we rusned home and it was 103.so i ran him under cool water to cool him off quickly since i assumed he was in 103 temp for over 2 hours but he cooled quickly so i didnt do it long and as i was going to put him back i candled and saw what looked like his little body breathing right under air cell, you know how their bodies move fast breathing, and so as im leaning him back in the incubator he kicked inside the egg real hard. This being my first time hatching eggs i was so happy i hadnt killed him! It was his hatch day but since he was small i figured he'd be a day or two late. So i put him back and kept peeking no pips so before bed i candled him and i can see what i think is a beak and his feathers and his body that was "breathing" but is no longer any movement what so ever. And he cooled off quickly doesnt seem he is holding any heat. So i float tested him and he floats right at his air cell maybe 15-20 percent.
Now my questions are, if he looked to be breathing dont u think he pipped internally? And if when i moved him, i messed up his position which is why he kicked and i killed him then? But if he pipped internally wouldnt he float high or sink, not float right at his air cell? Can a chick be dead and float perfectly at the air cell? There was no rocking. I can barley see any veins so i think they have disenegrated, last night i thought i saw the yolk sack wasnt absorbed yet but i could be wrong. Now im at a loss of what to do with humidty, what day hes on, if its super bad i keep moving him and turning him, i def think hes dead. Theres no sign of life. But i suppose the 6 i had that hatched some didnt show life either on day 18 but why would he be "breathing" and then kick so hard and now not move? I just cant figure out why if he was breathing (which should have dawned on me then but i didnt put it together anf his air cell wasnt big enough, i have a lot going on at the house right now with family so it was overwhelming at the time) because he pipped internally why would the float test show a viable egg as if the air sack is intact? Can this test sometimes be wrong?


Thank u for any thoughts advice or self experience!!!

Simply floating does not indicate anything other than that there is air in the shell.

Movement of the egg, on its own, in the water indicates life.

If the egg doesn't smell you can leave it in the incubator a little longer but with the rest of your description, my guess would be that it had too much fluid left in the shell when it pipped, and when you moved it, it drowned. Or the sudden shock in body temperature could have caused his death. Sorry!

See thats what i figured aw that sucks! When they were in the beginning of 3rd week that happened before and i ran them under the cool water because its what i read on a site to do and they all same out fine but i think he should have been in lockdown the air cell was too small and i would assume the temperature would affect them more quickly when they are full grown like that? i hate the thought i killed him!! If we hadnt left the house hed be fine right now. I do some stupid stuff sometimes! Lol just dont think until its too late. I needed a second opinion, thank you!

I was wondering for future reference, say when i found him "breathing" like that and i knewnhis air sack was too small, would it have been a good idea to try and break away a little of the shell at the air sack area to try and get air in liquid out? Or is it just tok late when theyre ready to come out and air cell is too small? Nothing u can do?

The best thing to do, if you know that your incubator conditions vary from place to place, is to periodically rotate the eggs around in the incubator. That will keep them somewhat averaged out in development.

Breaking the shell would likely have been as immediately fatal. If you were lucky, you may have been able to break into the air cell and allow some liquid to drain. The better approach to a bad situation would be to attempt the hatch upright in an egg carton.

I am pretty sure it was the thermal shock that took this one out, though. Allowing the egg to cool down on its own would have been safer than shock chilling.
