WE've had alot of noise and even some rocking for 2 days now but no pips. I'm wondering how long do they peep before they pip? I'm very worried they are spending their energy making noise in stead of making holes and they will just give up. My last 2 hatches, there was practically no noise until righ before the hatch. When do I intervene....fyi I am on day 21 today but the noise has been going on for 2 days with nothing else.
