Was anything else placed in the unit (watermelon, other waterers, other seed, etc)?
Placing foreign objects in the Surrogator can often lead to unintended consequences ultimately leading to chick mortality. Seeds of any kind should never be placed in the unit as they can ultimately result in mortality. Cut up watermelon and tomatoes are beneficial and provide the birds with additional nutrients and can be placed in the unit whenever the birds reach 2 weeks of age, but never before.
