High HUMIDITY last three days.

[Roxannemc]

I understand high humidity in day 1 to 18 will cause death of chicks than can not hatch. But what about day 19 to 23 ??????

Day 18 on it has to be higher so the chick doesnt shrink wrap( membrane srs out trapping the chick while hatching) Your humidity needs to go to minimum 65 and optimum 80.Iwould aim for 70 ish my first hatch from day 18-23 . See how it goes for you .If youhave hatch problems then ajust down tr up next hatch,..
GOOD LUCK!
