This is Day 19 1/2 and Nothing happens.
Candled on day 18 and everything looked good at least 27/30 or them.
Temperature is at 99.5 average.
Whats going on?
I am using a Hova Bator incubator and did use an egg turner till late day 17.

Patience! I hardly ever see rocking or pipping until mid Day 20 or later, and if your incubator has a fan you may not be able to hear the peeping associated with internal pips over the sound of the fan. Try not to worry.
