Yes, it’s a pip. If it were mine, I’d give it a while and if it doesn’t make any progress maybe chip off a piece of the shell, if it still doesn’t make much progress you may (or may not) have to assist. GOOD LUCK!!
OH!! I'm so excited for you!! Ours hasn't started pipping yet but I swear I've seen a few rock last night. The waiting is killing me! Post more pictures so I can live vicariously through your hatch! lol
If chicky's made that much progress being upside down, I think they're going to be okay. One of mine pipped like that, zipped out no problem. Just keep an eye on them. Wishing you luck!
