well, so much for me not posting ..
I have 3 GQF sportsmans that run about 7 to 8 months of the year.. I have developed a method where I can go from the normal 280 eggs per unit up to almost 500.. (chicken)
I actually have 46 goose eggs going right now,, first ones due on the 19th.. I do not have a good record with goose eggs.. usually not more than 50%.. despite my overactive ganders, I end up with a lot of clears..
with chickens I get easily 80% and seldom 100%.. I include the clears as part of the failures.. I have had people tell me that they constatly get 100% hatches.. to them I say, good for you, and don't try to Bull S--t me..
I don't go nutsy about humidity, or turning.. I hold 99F as I cannot read 99.5% on any of my thermometers..
I keep the humidity at 45% to 55% during incubation.. If I can raise it during hatching, I do, but usually I don't have sticky chicks..
If I have to stop the turners during hatching for some eggs, I don't feel that it hurts the incubating eggs to not turn for a day..
I constantly have staggered hatches.
No matter what people on the incubating thread say, if their eggs are hatching on day 19/20, despite what they claim their thermometer reads, the temperature is too high..
also if a chick gets glued inside it's shell, 99% of the time, you opened the hatcher when it was pipped.. I know you did, and you know you did.. fresh air will turn albumen instantly to glue..
even Superman is not fast enough to open and close an incubator to prevent this..
I am willing to bet that nobody on BYC has a thermometer delicate enough to measure the difference of temperature from the top of an egg to the bottom.. or even from the top of a styrofoam incubator to the bottom..
If your incubator is properly preset for temperature before you add eggs, you will not have 110F temperature spikes.. Unless the room you have the incubator in goes to 110F.. If you have a temp spike, it is bause you fiddled with the temp setting after the eggs are installed..
the main cause of styrofoam temperature settings and humidity settings fluctuating is not because of the settings.. It is because of air leakage mainly around the seam where the top sets on the bottom.. tape it with duct tape all around.. problem solved..
sorry this went into book form..

yes I wash my eggs.. I am not in the business of incubation pooh..
This is the way that works for me.
I do not wash my eggs for incubation, I never set any dirty eggs. I have 3 types of incubators I use. An old Lyons transparent hen that is a still air, a 1583 forced air Hovabator and an older
Brinsea 40. All have been set to temps that work in my house and never adjusted. 99.8 I use a digital temp/hygrometer in each. I keep my humidity levels around the 40% mark the first 18 days. Bump to 65 to 70% the last 3. If I hand turn as I do in the old Lyons or the
Brinsea 9i don't use the cradle that is with it) I try to turn 3 times a day. I have forgotten before or was away and could turn for a day without any ill results. I've never had sticky chicks, I do not help chicks out of the shell and mine usually hatch on day 21. I have had at times 100% hatches from shipped or my own. I do not takes the chicks out of the incubators til the hatch is done.
