Temperature question... Brinsea Polyhatch

[Emmet Mcknight]

I'm going to use a Brinsea Polyhatch for lockdown days only, I'm incubating in a Brinsea Oct20 Advance and currently have 3 sets of eggs in there, first set is for lock down on Monday so will be removed to the Polyhatch.

This is the first time I have used the Polyhatch, its a still air for those of you who don't know the model, its regarded as one of the best, question is this... Are you better being on the higher side of the recommended temperature or the lower side? (lock down days only) I'm struggling to get my thermometers to agree, the glass thermometer that comes with the incubator is reading 39.2 celsius at what I guess to be the top of the egg (this is what the manual advises), my other two digital thermometers are reading 37.5 & 37.9.

Is temperature critical in the last 3 days? I'm also struggling with getting the humidity above 50% and thats with the 2 trays full and 3 air holes covered, I know I can add another tray if I want but I'm just curious as to what others have experienced???

Any input much appreciated. Thanks

Still air is recommended at 101-102F (38ish C) but some people lower a degree or two at hatch (I don't personally.) It's better to be a degree lower than a degree higher.

I use wet sponges in my bator for humidity, some use wet cloth. I just recently read where someone used felt to wick from the water wells. Basically anything sterile that will increase the surface area of the water.
