Well, softies are not unusual with new layers, but I think this girl is a bit neurotic and thus stressed out...and/or she could be a 'lemon' with a wonky shell gland.What causes the soft egg?
The clump of gunk appears to be shelling or membrane material.
There is a very thin layer of shell on the entire egg.
I assume the intact egg, found on coop floor about 9 last night, came from a different bird.
