Day 18, egg cracked

[alexthefarmlady]

These are pictures of the egg that cracked at day 18. The shell came off easily; near the big end there was some fluid underneath the shell as it peeled. There was a small amount of fluid seeping out of the membrane where the air cell would’ve been. Very little embryonic fluid was present. What do you guys think?

@WVduckchick, @Pyxis, @Ravynscroft, @ronott1, @ChickenCanoe are some of the many people with hatching experience that might have some info for you.

I'm not sure what the question is. Apparently it died when the shell cracked or near that time. Perhaps bacteria entered the egg. Always when an egg cracks, it loses moisture rapidly.
Sealing the crack completely ASAP is the best course of action. In the past I had used both beeswax and nail polish to no avail. More recently, I've been using liquid skin bandage and have had eggs successfully hatch. I once dropped an egg around day 14 which was cracked over about 40% of the shell. I took a chance and covered all cracks with liquid skin and it hatched on time with no problems.
The liquid skin has antiseptic properties which likely help.
