Hatchting failed?

[Stacyoung13]

OK great thank you. I can't here chirping but the incubator is really loud. I can see movement in the bit that is open that looks like breathing, but it has not opened more for hours. Should I still not intervene. I am keeping the incubator closed at the moment, but will definitely candle when I open it. Just not sure I should do that with the one chick hatchting?

It can take up to 24 hours or so to hatch after pip. Don’t open unless you have to, you want to keep the humidity up. If you do open, then candle, have a spray bottle with warm water to mist eggs and bring humidity back up. Good luck, keep us updated!!

What is the humidity set at?

At the moment it's reading 67%. But to honest I don't trust it at all as the temperature reading is so wrong.

I posted this on another thread. One reason the chicks may hatch late is because the temperature was a little low and if the temperature is a little high they may hatch a bit early. My earliest hatch was on day 19, my latest hatch was on day 25. These were different hatches. Also I have had my best hatches when I keep my humidity around 35% during incubation and up around 75% during lock-down. Good luck and have fun...

This is what I do.
Whenever I purchase a new thermometer and about to use it for the first time, I calibrate it. Thermometers will also need to be calibrated whenever they are dropped or when going from one temperature extreme to another. Thermometers are a critical measuring equipment's for temperature to ensure good hatch rates.

There are two methods that you could use to calibrate thermometers -

Ice Point Method - Fill a container with crushed ice and water. Ensure that the container has enough crushed ice to provide an environment of 32 degrees F, so you may need to add more ice into the container during the process. It will takes about 4 to 5 minutes for the mixture of water to stabilized. Then insert the thermometer which needs to be calibrated into the appropriate immersion depth. Hold the thermometer away from the bottom and sides of the container to avoid error. If your thermometer is not accurate at 32 degrees F, adjust the thermometer accordingly.
Some Thermometers are adjustable and some are not.

Boiling Point Method - Fill a container with distilled water and heat it up. After the temperature in the water has reached the boiling point, insert the thermometer . Be sure to leave at least a two inch gap between the thermometer sensing element and the bottom and sides of the container to avoid error. If your thermometer is not accurate at 212 degrees F, adjust the thermometer accordingly.
Again some Thermometers are adjustable and some are not. If the thermometer is off just note the difference.

There are some thermometers that are not meant to be put in water and water may damage them. This is what I do for these types of thermometers. I fill a glass with crushed ice (NO WATER) and put the thermometer probe around halfway down into the ice and cover with a washcloth. I let the thermometer set in the ice for about 15 minutes. At that time it should read around 32ºF.

I test my therms against a medical thermometer:
