I think this is the fastest I have had chicks hatching, I can looked into the hatcher no pips, half hour later I have 2 chicks in there.I put 17 eggs in the hatcher on Tuesday, 2 Buckeye, 7 Delaware, 6 Icelandic and 2 olive eggers. I now have 4 Icelandics, 2 Olive Eggers and 3 Delawares with all but 2 of he remaining eggs pipped, they should hatch out today. So 15 out of 17 eggs. The Icelandics hatched out on the 13th two days early. The chicks were due today. No complaining on this hatch. Another batch due to go in on Sat. At least I know my Icelandic and Delaware roosters are fertile boys. The Buckeye roo is trying, have 1 from another hatch, and should be 2 from this one, getting better.
