Hi everyone! This is my first time hatching, and I am probably being a worry wart; but last night at about 9:30 or 10 pm one of my chicks pipped, then zipped, its been 15 hours and it hasn't made any progress. I can see a little bits of its body poking out of the zip, and its chirping like crazy. But when it tries to roll around and get out of the egg, it can't and it just starts chirping again. I am really worried about it, and another egg pipped yesterday afternoon, but it hasn't made any progress either. But they are both still chirping and rolling the egg around. Should I assist? I am really scared that they might not make it. That's the zipping chick, does the membrane look dried out?? Thanks in advance!
