Gooey slim in nesting box with fresh eggs

[PrettyBirdRocky]

Okay, so not sure on what to call this. Second time this gooey slim has happened, and even prior had a shell-less egg. Photo of the eggs are what was in nest with the slim. It's not quite squished yolk/egg, but not quite sure what it is.

Background: five 22week black Australorp, so far three we know for sure have been laying every other day since 18/19 weeks. Flock mates include three younger BAs(18 weeks but they are not red nor as big as their older BAs), 4 each of Olive Eggers(14wk), Light Brahmas(16), Buff Orpingtons(13).

Nest boxes- crates with clover hay(from our farm)

Feed: Dumor Starer/grower, do plan on leaving them on this as they are in a large covered run but not free ranged. Four containers of feed free all day, 4 buckets waterers with sled with water(maybe inch or so with ice bricks for heat-brahmas use it most)

Treats- kale and cabbage, at times frozen cucumber, watermelon, blueberries (maybe once a week), scratch, handful maybe once a week. (Their main treat is wet mash food)

Dish of oyster pellets and grit. Trying to find flakes, have ground up the pellets/chunks and eggshells.

Adding, the last girl on the nest box was out black banded BA who last Friday during our no wind 90dF weather had heat issues during the night, we did get her cooled off and haven't had a heat wave since. (I know some parts of US have been bad but here in central Indiana we've experienced mid 80s with high humidity)

But

Since then all have been looking fine, active, talkative.

(Don't mind the tarp and bungees we had a rain issue and did what we needed at the time lol venting is on all sides)

Sounds like a broken egg that got mostly eaten.
Sometimes all you'll find is a wet spot.
