Good Morning!
Update: (Briarwood Orps)
Status: Eggs held for 24hrs at 19*C before being placed in incubator.
Day 18: April 8th 2013
Hatch: April 12th 2013
Day 1
Eggs are all snuggled warm and inside the Sportsman. The temp is 99.5*F and the Humidity is holding at 53%
Turn count: 15

My first two hatches were not very good this year, I stored the eggs out in my old office, not heated and it get's down to 8 degrees out there, I have moved them to the basement now and it is 15 degrees down there, the hatches have been much better since I started doing that.
Hey Jayme,
A fair amount of people have showed concern when I mention I store my hatching eggs at 8*C. I guess I should mention that I don't always store eggs for incubation at 8*C
Over the past few years from research, and our own experiences we have found that the longer you plan to store the eggs for incubation, the lower the holding temp must be.
For example if i am planning on holding eggs for 2 - 3 days then I will hold them at 13*C.
If I am holding the eggs for a max of 7 Days they are held at 8*C. and keeping the Humidity up is important, almost crucial
60-70% Humidity is ideal from my findings on storing the eggs.
My method for storing eggs come from a rather long list of researching other's findings and experimenting with them, taking bits and pieces where I see they fit into my hatching program. Most of the articles I have been reading and coming across are heavily based upon broiler and commercial meat birds.
One of articles that I read can be found here. (UofA)

I also mentioned that I temper the eggs by removing them from the cold storage to room temp infront of the bator for at least 6 hours, and then into the bator. This greatly reduces sweating of the eggs. I climatizing the eggs between storage and placing in the bator they will develop better.

Maybe, would you like me to start a new thread to talk about incubation stuff so that you don't get this thread muddled up? Cause I would like to know who else hatches at a lower temperature. I never change my temperature during hatching, ever, and now wonder if my hatches would be way better if I did. Although for the most part I am pretty satisfied with my temperatures. Have an awesome day, CynthiaM.
Hey Cynthia,
There is a major reason why we have the hatch temp at 95*F in the Hovabator ONLY.
from trial and error we have found that this temp works best for us when hatching.
Remember developing chicks can handle a temperature drop of a few degrees rather than a spike of a few degrees,
Ie: Temps goes from 99.5*F - 95*F they will be ok, for the most part. (lots of variable factors involved, humidity, strength of genetics of breed and so on)
Temp spikes by even a few degrees and they more often then not will parish, but not always.
For the last few years we have played around with our hovabators and incubating / hatching in them.
We found it difficult to maintain the temperature in the hovabators at 99.5-100*F after day 18-19. The temps were spiking to 101-102. We lost chicks, This happened our first few hatches. Not a total loss, but reduced hatch/survival rates.
We then started to incubate in one and hatch in another, moving the eggs from one hovabator into another. Both at 99.5*F
What we noticed then was a spike in temp after the eggs only being in there 12hrs roughly day 19. Temps had risen by 1 degrees, and was reading 101.3*F by day 20
I started scratching my brain and dad and myself started then to play around with the hovabators, bought a third one to use as a control.We thought that our hovabators we just super sensitive, and tried to fine tune over a number of hatches we did.
It was mutually agreed upon, that by day 18 of incubation the soon to be hatching eggs were producing their own heat, this was determined by doing a series of surface temp readings spanned out over a few hatches. I am not saying that the eggs them selves produced that much heat, but they contributed to the rise in temp.
Other contributors were, not opening the bator, using warm water to increase humidity, as well as fluctuating room temps.
We then started to drop the temp down to 95*F and 80% humidity and found that our hatch rates were much better in the hovabator.
Last year we bought the Sportsman, and decided not to hatch in it, and hatched in the hovabators. Worked really well. Hatch rates were in the 90% + range for most chicken hatches, and 96%+ for Turkeys.
The only and MAIN reason we drop the temp down is that the hovabators are so "touchy" I'd rather have them have a slower longer hatch, then to cook before pipping.
I find that Cabinet incubators are way more accurate, superior and reliable. The can hold temps/humidity better, than the Styrofoam models. If I were to use the Sportsman for hatching, I wouldn't decrease the temp, just increase humidity.
Just don't like the idea of having to clean up after every hatch.
Cheers,
Jonny.
