It makes it go down. Going down is good at hatch, so if it goes down to 98.5 or 99 it is a good thing.
I should add more I suppose.
I read some research articles where they experimented with lower temps and chicks hatched fine down to low temperatures. They hatched faster and recovered more quickly.
It is probably in part due to more oxygen. O2 goes down with heat and humidity. Somewhere over 80% humidity ant 100 degrees and the chicks suffocate. If a lot of chicks hatch at one time, Humidity can get into that range quickly.
Ok, how low is "lower temps"? and is this done on the very last day or when?
That makes sense about lower O2 with heat and humidity. Explains why its so hard to breathe in Minnesota in the summer! Ugh!
Here's what I've done with my incubator for now. Come summer, I hope to be able to do something else.
I started running the incubator with the number 6 switch toggled up, like it was before. I added a 4 watt candelabra bulb to increase the heat slightly. At first it stayed right at 100* for a while and then it started dropping and dropped to 98* I toggled 6 down and put 7 up and the performance was repeated, exactly. Then I put in a 7 watt bulb and it climbed up to 101* but then several hours later, it went back down to 98. So then this morning, I put a 15 watt bulb in there and the temperature went up to 102 and stayed there for several hours. This afternoon, I went in and toggled 7 down and put 3 up. The temperature dropped to 100. So, I left it there for several hours to see how it would do and around 10pm tonight it was still at 100 so I loaded it up with eggs. I'll be watching it closely to see what happens. I really hope this temperature can be sustained. I cannot afford a new incubator right now.
I need to get another thermometer/hygrometer for my hatcher, which is in "lock down" now. Not really, but I won't be messing with them. I've learned to keep my paws off! After I'm certain the incubator is staying steady, I'll take that little instrument and put it in my hatcher... gotta keep track of two places with one machine!
Oh, by the way, I candled all the eggs in the hatcher tonight and there is only one that doesn't appear to have survived the 102, but if I remember correctly, that one didn't look exactly right before that either so, it probably won't hatch. That means there are 18 of them in there that should hatch. If they all do, I'll be shocked and amazed! Playing with the humidity and whatnot over the last couple weeks, I have gotten them to where they are underweight by about a half ounce, and that is for 19 eggs. One of them had a pretty large air cell so we'll see if that one gets shrink wrapped.
