Great to hear you are persevering Polished Arrow. The only crime if mistakes are made is if you learn nothing from them.....
If you have a clutch of fertilised eggs and a broody hen, then why don't you just put the eggs under her bottom now?? She'll do a much better job of incubating them than any man-made incy will do......... plus you don't have to worry about power cuts, humidity levels and the like......
Just a thought.......
