I got 8 cochin bantam frizzle eggs in ebay. One wasn't fertilized after I candled at day 7. The others developed nicely. They were at 98 to 100. Could have gotten a little cold or a little warm but I adjusted as soon as I noticed. Turned them two or three times a day. On day 16 or 17 I found my disappearing hen (easter egger bantam) who it turns out was broody. So I gave her the eggs. 3 hatched and two died. :-( the one chick is doing great. I want to try again but I'm afraid. I have read about having three thermometers. Should I do that? Last time I had silkie eggs. I had two mamas sitting on 6 and got 3. They would leave some out and they got cold or pooped on. So I know what happened there.
