Crop is also full of liquid, but it’s clear and does not smell. White leghorn 3 yrs. Was laying eggs 2 mos ago, stopped and had a little bit of water belly. Avian Vet drained and observed hint of milky yellow and put her on antibiotic. Couple weeks later she was laying eggs again, but 3-4 weeks later stopped again. Vet checked again didn’t feel any eggs inside or tumors, no water belly, so put her back on antibiotics
