Are these yellowish blotches which appeared on my chickens white feathers a disease symptom?

The short answer is no, the yellowing of white feathers does not indicate poor health or disease.

Causes of yellowing are genetics, feed such as cracked corn and even eating green veggies and grass, the sun bringing out the brassiness in the while plumage, and one of the biggest causes is having the misfortune of getting pooped on.
