Today is day 21 for my hatch and this is my first time doing this so Im nervous... We had our first pip at 5 am this morning and still no zip... should i be concerned... i have 10 eggs of which im sure 8 had babys last i candled. Im not sure which egg the chirping is coming from!!! 5 of the 10 have pipped throughout today but just tiny bumps in the shell nothing more.. the first one to pip has pushed the pip a little further out about 1 pm. were going on 14 hours without zip... what should i do??? is this normal?
