Thanks for your input! The only reason I'm worried, is that I cannot see the air cell anymore, which makes me think the chick is in it and breathing, but unable to get new external air because it has not pipped. I put a tiny hole in the air cell section and am leaving it to do the rest on it's own. I did hear tiny peck sounds when I tried listening to it while hiding in the closet (only quiet place in our home!) so I know it's still alive - Hooray!venymay, I am not an expert, and I have not incubated many hatches, but I can tell you that 5 of the 10 that ended up hatching for me this HAL, hatched late on day 22, and they didn't pip before this day. Another 4 pipped and hatched today, day 23, and the tenth chick is just now hatching, never saw a pip (and I HAVE been looking, believe me). I am NOT a meddler, but if I thought I could improve the chicks' chances of hatching, I might check them (are any chirping?) and then follow advice. Oddly enough, I can NEVER hear chirping because I am deaf, but if I think about it at lockdown, I can put the amplifier section of my PocketTalker into the bator and listen for chirps through the earphones dangling outside. That's pretty fun, and it takes some of the mystery out of whether I got any wannabe hatchers in there or not. I wish this could be more helpful. You will get help from this forum.
