Nurture Right 360 Inside vs. Outside Ring

[MerryFeather]

I have a Nurture Right 360 incubator and have tried 2 batches of 4 duck eggs each. Always on the inside ring as I thought that would have the most stable temperatures. I only had 1 egg hatch successfully. I have been testing my incubators with various trials after our hatch. I have found with my Govee and other thermometers that the inside ring is usually over a whole degree lower than the outside ring. Has anyone else found this to be true for their NR 360 incubators?

I haven't personally (but I haven't incubated in the inner ring yet) but I've heard of some others having trouble with it. Check out the active NR360 thread.

I hatch Hookbills which are prone to low hatch rates and I hatch with several Nurture Right 360s with no issues. What temp and humidity are you hatching at? Are you using digital or analog thermometers and hydrometers? Are you getting the eggs from the same source? Did you sterilize the incubator before use and after each use (even new incubators need sterilized)? I would also recommend contacting the manufacturer and ask for re-calibration instructions.

Every few days I switch the position of all my eggs, to make sure if there’s a cold or hot spot they don’t spend the entire 21 days there.

I didn't think to do this earlier. It's late for me now, on day 18. I have a Govee hygrometer/thermometer that I put in one cell of the turner. You could definitely see variation in temperature depending on where the thermometer was in the rotation.

I tried the first hatches at 99.5 F and 45-55% humidity. In the inner ring. I added multiple thermometers and hygrometers throughout. They were initially reading 99.5 for the first days but eventually I think were running cooler. I have tried both digital and alcohol thermometers and tried to calibrate them but am unsure the ice water method of calibration is all that accurate. I currently have another attempt going in my NR360. I did a diluted bleach cleaning before starting and have 3 thermometers going. I also bumped the temp to 100.5 according to the incubator but I think it is actually holding a 99.5 average according to my Govee. The outside ring is about a degree above the inside ring. All the eggs are from our own ducks. They are healthy as far as I can tell. I did some rounds of vitamins before we collected again. Just incase.

You may need to rotate the eggs from both the inner and outer circle throughout incubation. I know you said that you disinfect the incubator, but do you also disinfectant the thermometers and hygrometers? Since they are your own eggs I would try a dry hatch. I started dry hatching and my hatch rates have gone up even more. However, there is always the possibility that you have a duddy incubator

I did my best to disinfect the thermometers. All I could figure to do was wipe them with disinfectant wipes and let them dry but I can't get them wet really.

On your dry hatch, how low does your humidity sit at? When I ran them dry during my tests the humidity normally sat in the 10s somewhere. Even though the room humidity is usually in the 40s. Do you hatch duck eggs or chicken eggs? I thought it could just be my incubator but I bought another one and none of the eggs hatched in that attempt. I think it ran even lower and had bigger temp swings. What kind of thermometer do you use in your incubator as a backup?

Yes, mine is exactly like this. Perfect temps on the outer ring and 98.0-98.5 on the inside ring. I only realized after I just finished a hatch last Friday. I had marked the inner ring eggs. I think 14 out of 16 outer ring eggs hatched, but only 2 out of 6 inner ring eggs hatched. Both those 2 inner ring eggs hatched later than the others, AND one has an umbilical hernia.
I played around after the hatch, and if I raise the outer ring to 100.0-100.5, the inner ring seems to get to 99.3-5 so hopefully that will be a good compromise for both rings.
