Jackie, I came in just to see how your chick is doing. I am sorry to hear it didnt' hatch yet, but it is still possible. Especially as other chicks hatch and make noise, it might encourage the little one. I am not a believer in helping chicks hatch, but I will say it is an individual decision. If you really want to help, as long as you wait 24 hours after pip, you may be safe. But please be prepared that when chicks don't hatch on their own, they typically do not do well or have something wrong with them, which is why I dont' help anymore. Good luck and congrats on the babies that did hatch.
Jody
