I am most certain someone before me has asked this question; my birds are leaving butterscotch pudding color and consistancy droppings(some will show signs of the white swirled in, but most of the time not) . It is most of the time, we have not had any eggs from moult to now (normal), their combs seem pale and powdery. They race and run, sing and are eating well. They have not been having different grain or treats. Any suggestions?
