I really don't know, She was fine last night, and she seemed fine this morning, the egg shell didn't have much poo on it, I'm thinking the last 4-6 hours?
one of my hens had a broken egg in her vent, I cleaned her up and now have her in the house, but her vent and backside is very swollen. is there anything I can do to help. she calm right now and puffed up a little. It smells too, not rotten, just bad, like sour poo.
