Need Help Interpreting Float Test Results

[wolfandfinch]

Let me know if the pic doesn't show up. I'm on my phone.


Background: eggs are in the classroom, in a hovaBator 1583. I can't get in after 3 or on the weekends. Lockdown was last Friday 3 pm after I took out the egg turner. Monday at 7am I came back and the temp was down to 94 Also not sure of humidity because I don't have a hygrometer (will buy one for next hatch). Followed the manual regarding filling troughs but screwed up and took out the red vent on day 21 thinking they might hatch and need oxygen. Have never seen moisture on the window.

Day 23. Candling showed no internal pip and no movement. No tapping, chirping etc either. I tapped on the shells before and during candling. Air cells had grown since day 18 but chicks aren't filling up entire available space. Some do but not all.

Moved to float test as per the learning centre's guide to assisted hatching. 2 eggs did a quite high float confirming what I saw when candling. 9 eggs looked like the picture above and floated lower but not completely under the water - the air cell only was above. I thought they'd need to float submerged to pass but am hoping I'm wrong. Thoughts? I can go as late as Friday (day 25).

Bump - I read another blog that talks about them floating vertically versus on an angle. Is there any weight to that one? Anyone have any thoughts?

Anyone?

If you place the egg in the water and the egg goes from completely still to bobbing, they are still alive. However, if they were at 94 F for more than a few hours, I would guess that they might be dead (being that it is day 23) I would "Eggtopsy" them tonight (start at the air cell portion first, if you see movement or blood... STOP and put them back in the incubator.

thanks. I didn't get any movement in the water. I can't get at them again until 7am tomorrow and even then I have only a little time before I have to run to work. I might wait until Friday for the eggstopsy so I have more time... unless have reason to think they need help with an external pip...
