I agree, I would help. I was in the same situation a week ago with one of mine. It was chirping for almost a full day without a pip and I didn't know if I should help or wait longer. I finally decided to help so I made a small pip in the air cell and removed just a small portion of the shell. The next morning nothing else had happened and the chirping was at a minimum. It was day 22 so I knew it should be fully developed and ready to come out, but for some reason couldn't. I decided to take it out of the incubator and into the bathroom - turned the shower on all the way on hot to keep the humidity up in the room with the door shut and put it on a towel. I started chipping (ever so gently) some of the shell away and it started to push it's way out. Turns out that my humidity in the bator was low (hygrometer was not reading right) and it was starting to shrink wrap in it's shell. It wouldn't have made it if I didn't help. He hatched completely and is almost 2 wks old and doing great! It's extremely scary and nerve wracking - I shook like crazy, but it's worth giving it a chance. Good luck!I have just candeld it (I put the mattress up against the window and made a tent with the duvet) and I could see something that could of been a beak and it was moving forwards and backwards but I couldn't hear it pecking the shell. would you still assist or give it a bit more time? sorry I am such a worrier
