Help did I ruin my hatch with wrong temperature??

[pineapple416]

I have been incubating a batch of eggs for the past about a week now and I think I might have ruined it. Last night the temp was running a tiny bit high, so I moved the notch back a tiny bit, forgot to check up on it, and fell asleep. I woke up and it was between 95 and 96 degrees F, while I usually keep it at 99.5 degrees F. Did I completely destroy my hatch or is there hope that they are okay?? Thanks everyone.

Oh by the way is 60 percent humidity too high for a hatch?
Thanks again.

The following is all assuming you have guaranteed accurate thermometer and hygrometer or ones that have been calibrated.
60% is likely too high.
You didn't kill them if 95F overnight.

What happens if humidity is too high?

 

[ChickenCanoe]

In a nutshell, the egg won't lose enough moisture and grow the air cell properly.
Problems associated with that are:
full term embryos dying
chicks hatch late
sticky chicks with smeared albumen
unhealed or infected navels
malpositioned chicks
broad pip area due to small air cell and chick can't break through

What happens if humidity is too high?

The air cell stays to small allowing the chicks to grow too large and MAYBE not be able to turn into position to pip and hatch. 45% is my preferred humidity. Egg color effects this slightly.

They could also try to internally pip to be met with water and drowned instead of hatching.

Or they may simply be very wet at hatch.

I doubt that 95 over night will destroy hatch all together, and I certainly wouldn't give up!

Just candle at your next scheduled time and see how things are going.

Humidity is currently at about 56% so I think it should be okay for now. Temp is stable at 99.5 again woo woo!

Okay thanks for the info I will try to lower it.

I would let the humidity drop more.
Most people candle to insure air cell is growing but I weigh eggs to determine proper humidity. I don't even own a hygrometer.

Thank you I will try to decrease humidity. I was planning on candling today because I'm excited but it's day 6, is that too early?

It may be early to tell how the embryo is growing depending on shell color but you should be able to determine air cell growth.
