My King Hen which wasn't eating, had a mucky vent and was hunched up on the floor, is on the mend.I gave her a small dose of extra virgin Olive oil and the next day She had puked-up a compacted lump of food about an inch long by 1/2 inch wide. She's really bright today so gave her some food which I first gave a quick wizz in the Wifes coffee grinder to break it up a bit and She's eating!. Don't know what caused Her crop to compact like that. Hoping it doesn't happen again. Any words of wisdom?
