I think chicks pip and then don't do anything for 10-12 more hours just to drive us nuts. If you can see them moving and hear them chirping, I would give them more time. The first pip tires them out some, so they rest before they start zipping out, sometimes this can take up to 24 hours. This is the hard part, when you have to use the judgement call on when to help. I start helping when I feel life is slipping away. Lots of good luck coming your way!!!
