New to hatching - Incubator Question

[Khelms829]

Temps can also vary in different spots in smaller incubators

It’s not rising above 98.5… but it’s not going below that 98.5 is that a safe temp range for hatching

What temp have they been at for 1st 19 days? I drop temp about 1 degree during lockdown others don't drop temp at all.

98.5 - 99 you should be fine in forced air incubator which is what yours is if its a 4250. Only reason for drop in temp is because of rise in humidity makes for less oxygen and harder for them to breath. so only need to drop temp if you use a high humidity for lockdown.

They’ve been in a constant temp of 100.3 in the other incubator since I started incubating them

Humidity in the Chinese one has been a pain in the butt. But it’s been between 45-50% for the first 19 days

You could go to 99 degrees to be safe from dropping below 98.5. What humidity do you plan on running for lockdown?

Hey I hung the thermo probe from the roof of the incubator to about even with where the egg is and it’s reading about 100 to 100.2. Humidity is 65% on the digital readout on the incubator and 55% on my hygrometer. I’ve tried adding water and it doesn’t go up above 60% and doesn’t seem to stay up. Is 55% safe for humidity?

 

[Huntmaster]

I would try to keep temp around 99 degrees, 60% humidity should be fine looks like I can see condensation on window of incubator so your humidity should be high enough. I like it around 65% to 75%. To get it higher if needed I use wet sponges in incubator.

@Khelms829, how are your eggs doing? Do you by chance have one of thse that you could measure the shell temp with?
