Was the classroom incubator still air or forced air? Forced air incubators should be set at 99.5 and still air should be set at 102, I think.Okay and I know it's not really muscovy related but I'm incubating a mallard Rouen hybrid egg and it's been in a class room incubator like u know the kind with really bad temperatures and u have to turn it twice a day well it's been in that incubator for around I want to say14 to 18 days, and the embryo hasn't grown much but it's alive , and so I moved it to my incubator that turns hourly on Thursday and I candled it and now the embryo looks a lot bigger like it's at the point where it's almost ready to internally pip, I don't know if that's possible but I know what I saw, could it be possible that I didn't candle it right before I moved it? And is it safe that I'm putting the egg in an incubator with a higher temp ( the small incubator was on like 80 or 90 degrees and now it's on 99.5) or did the classroom incubator just store the egg and put it in a state of stability till it was ready to be incubated. I don't know if that this paragraph makes since because of the sentence structure , since I'm not trying to use school right now.

Temperature
Most avian species incubate best at a mean temperature of 37 to 38°C (98.6 to 100.4°F)
Waterfowl are best kept at 37 to 37.5°C (98.6 to 99.5°F). In forced draught incubators this
would be the temperature indicated on the thermometer.
In still air machines the temperature indicated would depend on the position of the
thermometer, which is quite critical - so follow the instructions carefully about adjusting the
height. It will also depend on the construction and temperature gradient in the incubator, so
again, follow the instructions.
In the absence of instructions set the thermometer just clear of the top of the eggs and run the incubator at an indicated temperature of 39 to 39.5°C (102.2 to 103°F).
It is important to appreciate that no incubator has perfect temperature distribution. Heat losses
from the cabinet must be balanced by heat provided by the heater.
The process of transferring heat from one to the other necessarily involves a temperature drop
- even with a fan- and this drop will mean that some eggs are warmer than others.
To keep these differences small, operate the incubator in warm, steady conditions.
Ideally use a thermostatic electric convector heater to maintain a steady room temperature of
20 to 25°C, day and night.
