My Welsh Harlequin Poppy emerged from the coop this morning with an enlarged crop. Her head is kind of tucked down on the crop, as in the photo. I have zero experience with this. She seemed normal yesterday, although I didn't observe her much from late afternoon until bedtime. She's eating and drinking and swimming and is able to preen her belly, but she seems to be walking with less energy, and she also seemed to have difficulty bending down to pick a pea up off the ground. After reading a few threads here I gave her some olive oil and massaged her crop, and added ACV to her drinking water. Is there something else I should be doing, aside from an emergency vet visit? Will this type of thing ever resolve on its own? She ate nothing out of the ordinary yesterday - just Mazuri, some meal worms, and bites of kale.
