I'm using a still air Brower 845 incubator. The instructions said to stabilize the temp between 101-102. I let temp steady at 100 - 102 for 24 hours...My digital thermometer (Accurite) has never settled on 101, which I don't understand? I set 16 silkie eggs on their sides on Friday (1-27-12) at 9am. The temperatures haven't stayed dead on, so I cover vent holes or open vent holes and occasionally adjust the screw. The temps have dropped to 97 at night a few times and during the day I've had to bump them back down (from 104 but it was very briefly before I got it lower.) It usually stays about 100. I have candled a few and seen some development, but also noticed very loose air cells from being shipped. I decided to place them in egg cartons and just 'tip' the little eggs from side to side to hopefully 'train' the air cell back to the fat side of the egg. I've been keeping the incubator between 97 and 99 degrees. (I can't get it to read 98??) Then I began to wonder...how much hotter is the temperature on the tops of the eggs? I placed a mercury thermometer on plastic and laid it across some eggs..............It went up to 104 and 106 when the digital thermometer was only showing 99? Can this be acurate and if so, should I adjust my incubator so the digital is reading 95 degrees? Or, should I lay them back down on their sides to avoid the higher heat? By the way, the eggs do not feel too hot when I touch them. They feel warm like an egg feels right after a chicken lays it. I would really appreciate some insight and experience. This is my first time incubating. I thought I did my research, but the real thing is so stressful.
