Im sure its been asked before but I cant seem to find what Im looking for. My question is, how long does it usually take? I have one egg that I rescued from a mama who abandoned her nest. I put it into a hatcher set up- the next night it pipped (last night) and today, its made no further progress. I can still hear it chirping. I dont intend to intervene at this point, if at all, I was just wondering how long it can take. How long can it go and still be on the normal side of the time-limit?
