Answer 2

It does not mean that there is anything wrong with your bird ,it could be that you have given him something different in his diet.

Think have you given it any fruit or greens these will change the colour also if it is coming into breeding condition ,this also affects the colour of their droppings.

But without knowing what species your bird is it is difficult to help.
