What are the main causes of watery whites (thin albumen) in fresh brown eggs?

Watery whites or thin albumen indicate a severe loss of internal egg quality, leading to flat yolks and poor consumer satisfaction. While egg aging naturally causes ovomucin proteins to liquefy, a sudden incidence of watery whites in freshly laid eggs points to pathology, most notably the Infectious Bronchitis (IB) virus. IB virus damages the epithelial cells of the oviduct magnum, where albumen is synthesized, preventing the formation of thick whites. High concentrations of vanadium in cheap feed phosphates also cause immediate albumen thinning. Wholesalers on Murghi Mandi discount watery batches as they fail retail grading standards. To combat this, farmers can research viral disease control in the Poultry Encyclopedia, source cold storage equipment and IB vaccines on Poultry Plaza, and check daily grade-wise pricing on Poultry Rates.
