drowning point?

About 75% during hatching. I think I lost one to drowning at 70% but there were other factors including a huge humidity spike shortly before I was suppose to stop turning. Dunno during incubating. It's hard to tell which ones drowned before the last 10 days or if something else happened.

that stinks guys!..sorry!...

so...its mainly during hatching then?...can it happen during incubation?....

I would think so but it would probably take a really high humidity to drown them more than a few days before hatching. The problems with high humidity during incubating usually shows up during hatching. Either the air cell is too small from lack of moisture lost or the chick drowns on the collected water in the egg when it goes to pip.

I think it is sometimes caused by high hum during incubation as the egg is not able to evaporate and create a air cell for the chick to breath when it pips.'

IM a firm believer in candeling and watching the air cell to see if it is getting to big or not big enough and adjust hum accordingly. There is an article in the Storey's chicken book that has illistrations on how the air cell should look at 3 critical times during incubation.

Never seen a chick drown in the egg, dont think they can.

But the air cell can be to small if the humidity is to high, and the chick will hatch as a stickey chick.

Drowning the chick would have water in the lungs.

To high humidity will cause them not to hatch ,but not drown. Lack of air in the cell.

I don't understand what your trying to say ? Sorry. The air cell will not be to big with high hum.

WooHoo!!!!! Hope you don't mind, RedHen!!!!!!!!! Hey guys, it wanted to open with "Corel Photo Shop", which I don't have, so it didn't work. Changed it to "Open With" Internet Explorer, now it works

!!!!

On topic: The chick takes it's first breaths while still in egg, when it pips into the air cell, a day or so PRIOR to pipping externally thru shell. If air cell practically non-existant or filled with moisture, I would imagine THIS is when chick could "drown" (or suffocate?). It's not using it's lungs before the "internal pip", so would say is technically impossible to "drown" prior! Did you guys read the thread started by Kryptoniteqhs, I think called "Excellent info here, everyone should read this" (something like that)... it is a really long thread, but goes into a TON of explanation, both "wet" and "dry" incubation methods are discussed & deeply debated! Would reccommend reading THAT as a "jumping off point" to anyone interested in humidity levels!
