One of my Black Australorps did not go to bed and I found her behind the door where she sometimes lays eggs. Earlier I found a broken egg behind the door along with a whole egg and assumed that one of them stepped on one of them and maybe ate part of it. Now tonight, she was sitting there on top of the broken egg with her face in the corner. When I lifted her, I found this: and when I looked at her vent, it was dripping what looked like albumin with some yolk mixed. She's got her tail down and acting very docile. Her vent looks like it's trying to push something out, but maybe that's how they always look. I don't know what happened nor what to do for her.
