I accidentally dropped an egg during lockdown last night, only about 4", but cracked the shell. Most of the cracks are over the air cell, and I did not tear the inner membranes (no leakage at all). I melted some food-grade paraffin and used a paintbrush to seal the cracks. I candled it, and the air cell was intact. The sealed area is only maybe 5-8% of the surface area of the shell over the air cell. The rest of the egg was just solid darkness. The chick in that one has always filled more of the space with dark, solid tissue than the rest, but I know it was moving 2 days previously. Has anyone done this and had success with hatching at egg cracked at this point? BTW, I went into lockdown a day early because my first hatch decided they were all coming out on Day 19! They had only been in lockdown for 12 hours before all of them hatched. Some of these eggs are also smallish, and I don't think the hens are terribly old, so I wanted to be prepared in case any of them pipped early, like my last batch. Thanks in advance!
