Hi, new member, new incubator (little giant styrofoam with fan). I have incubated a couple of other times. SO - start up the incubator, use the two five cent thermometers, follow the directions about water in one ring to start, both at the end. I had 12 araucauna eggs, 12 dominique eggs, and 12 buff orpington eggs. at 18 days, 7 of the buff eggs were clear and were disposed of when I removed the turner. (these were a friend's). at 19.5 days the first egg started to hatch, followed by 17 others. at 22 days, the last 3 buff chicks had zippered but were getting no-where after 18 hours trying, so I helped them and they lived. one was pretty sticky, but is ok. the bator was opened probably too often during hatch (I have a 6 year old), but I tried to keep it to a minimum. 8 of the araucauna eggs never pipped, so I took them to the barn at 22.5 days and opened them. they were dead, but fully formed though with a dime - nickle sized yolk outside. that would be about 18 days, which is when I removed the turner. those egg shells are so thick you cant see through them. What did I do wrong? I have set another batch today, with 6 thermometers in it. I am going to go a degree cooler than the nickel thermomter supplied with the unit says, which I think was reading too cool and making me keep the bator too hot. 2 of the other digital thermometers say 99.5 or so, but the third says 100 while the nickel one says 98. thermometers 5 and 6 are too hard to read, don't even know why I stuck them in there. tell me.
