I haven't hatched Keets before, but found this:
It depends on which day of incubation that you are on since keets can normally hatch anytime from the start of day 26 through day 28. A keet that has been pipped for 3 days is most likely either shrink wrapped or too big to be able to move around as it needs to in order to zip. If it was mine, I would assist, carefully, by zipping for it and removing the top of the egg. If it is shrink wrapped, gently moisten the membrane either with 100°F water or swabbing with coconut oil.
Thanks for your advice. Managed to carefully zip it. Looks healthy and strong. See pic.
TI haven't hatched Keets before, but found this:
"There really is no 'typical' hatch. Sometimes a keet will pip and zip in an hour. Others will pip then rest a few hours before they start zipping. Others will partially zip then rest. A keet can take up to 24 hours to hatch but I find that keets pop out of their eggs a whole lot faster than chicks do! "

To me it sound like your little one might have pipped not into the aircell, and is stuck. With chickens, I wouldn't expect a chick to still be alive after 3 days pipped. It's likely time to help, that is if you're willing to attempt assisting.
Here is an awesome resource for how to. There is a simplified one on BYC somewhere, but I don't seem to have it in my saved links.

I would like to say that even if you choose to assist, the likelihood of this little one surviving is very low.
Np, Glad you got a bebe.
Thank you very much for your comments. After reading your informative link, I assessed and assisted the keet. Membranes around the pipping hole were dry and inelastic. Looking healthy and strong.
Np, Glad you got a bebe.
