What is the Maxiumum temperature a duck egg can hatch at?

Simple question, please answer.

Do you mean actual temperature in the bator come hatching time, or maximum temperature an incubating egg can survive and still make it to hatch?

Currently my temperatures are betweeen 101.5 and 102 is that too hot?

Not for a still air incubator. That would be too hot for an incubator with a fan to move the air.

Erm, I am kinda new to this so I don't know what kind of incubator I have. I amk using a styrofoam cooler with mesh aire and a 23 watt light bulb.

A still air bator is one with no fan. A fan assisted one does have a fan.

You need to realise the crucial difference between the air temp and the internal temp of the egg. Changes in the air temp take quite a while to affect the internal temp of the egg. When you put all your eggs into your bator to start, it can take up to 24 hours for them all to come up to temperature. And it's the same when the temp in your bator changes.

Like, if you're having temp swings between say 95 and 105... If the temp is swinging up and down every ten minutes, its very likely that the internal temp of the egg will hold steady round about the middle point of 100F. But if your temps are swinging up and down slowly and staying high or low for hours at a time, your egg will be heating up and cooling down.

An air temp of 105 for a few minutes will most likely not kill a developing embryo, but an internal temp of 105 almost certainly will!

So to answer your question...

If your styro bator does not have a fan, and you're measuring your temps just above the eggs, 101-102 is ideal.
