Thermometer help!

Quote:

In a still air incubator (like yours) the air stratifies according to its temperature. The hottest air is in the top of the incubator and the coolest air is in the bottom. Generally the temperature in a still air incubator is measured at the tip top edge of the egg shell and it is considered best if the temperature there is 100 to 101 degrees, meaning that the temperature at the middle of the egg should be 99.5. degrees after stratification is factored in. That is why I don't use still air incubators because to me it is like trying to concoct a witches brew to get the hatch to come off right every time. Especially considering all the variables like normal daily air temperature, humidity, and the natural air flow outside and inside the incubator room, even the number of eggs developing in the bator will influence the temperature.

A hydrometer is a scientific instrument used to measure the specific gravity of a liquid (like beer or wine) and I don't see what that would do for a sitting of chicken eggs. I think you meant to type "psychrometer"

A psychrometer consists of two thermometers, one which is dry and one which is kept moist with water either dripping on or being sucked up by a sock or wick attached to the bulb. The two thermometers are called the dry-bulb thermometer and the wet-bulb thermometer. As water from the wick evaporates it lowers the temperature reading on the wet bulb thermometer so that it shows a lower temperature than that of the dry-bulb thermometer. By comparing the two temperature readings the humidity can be calculated using this scale......

Hope this helped answer some of your questions and that I didn't bring up more questions than I answered.

I meant to type Hygrometer, to measure the humidity of the bator. I just purchased a Brinsea Octagon 20 with the turning cradle that I will be using to incubate the hatching eggs I just ordered :) I'm excited to see the difference in the two bators.

That is a common error and one I have made myself many times. A Hygrometer is a new school devise and a Psychrometer is an old school devise. I use both to keep tabs on the humidity.

Isn't OCD a wonderful disease?
 
Ok so I candled all of my eggs today. 4 of them I could see movement in! 3 have veins and look like they are developing nicely. One looks clear to me, there are photos below the last one is the one I think is clear, but I would like a second opinion please :)

5 out of 7 have hatched! Still waiting on the last 2 :)

One of them hatched yesterday after noon and the rest hatched between 4-9:30 when I was out. They are dry this morning but not all fluffy, can I move them to the bator or should I wait another day?

Well the last two did not hatch :( looks like they pipped the wrong end. But I did just candle the eggs in my new brinsea bator and could see 7 moving!! I had to take 6 out due to 3 having blood rings and 3 being clear.

I can't really tell on some of the maran eggs so I will leave them in the bator for now :) I'm super excited to see what I get with my first hatch of eggs in my new bator :yiipchick. I will post pics when I get a better candler !
