Hello, This is my first round of incubating eggs. My eggs are polish bantam crossed with unknown bantam. Last night my egg pipped externally and it was more in the middle of the egg than on the big end. So I thought that I may have somehow cracked it and I sealed it gently back together with nail polish. Well I just checked on them again and it broke the seal, made the hole larger and is now chirping. I can see the little beak with an egg tooth. The chick however seems to be making the initial hole bigger instead of zipping. Since the hole is in the center should I help it sooner or just wait it out? And if it doesn't start zipping should I help zip? I have watched a few videos of helping if necessary, and I know it is best to wait til it is the last resort.
