49% seems low to me, the hatcher here is at 65% but our relative humidity is a bit high start with right now.
the hatch due 4/9 started early, 1 pip lastnight and hatched this afternoon another just hatched (both bantam cochins)
3 black Javas and 1 LF b/b/s Ameraucana pipped around 10PM tonight, one of the black Javas is already zipping.
