i'm hearing on the sfh thread that a number of people seem to be having problems with eggs quitting.yes, vent holes have been opened. The hatcher is a LG still air, temp 100-101 humidity at 60-65%. The eggs are swedish flowers I have hatched in the LG three other times with shipped eggs and they've hatched but these quit it seems.
i personally do NOT like still air. i added fans to all of mine (4). dry incubate thru day 18, then up to 60% (ish). my sfh are hatching just fine. (shipped and local). actually i'm doing better with shipped right now, but i think part of that is the local were pullet eggs. got 6 of the locals due on the 11th. 14 shipped due the 18th.
