Poop Checking

If i suspect my birds being ill, the first thing I do is check the droppings.

Then I refer to the two topics about poop identification in this section.

But I've found that they kind of contradict each other.

These are the poos I'm trying to identify the problem (if there is one)

The stool is coiled or partially coiled and varies in color from rich green to brown depending on the bird's diet. It will be green for birds on a seed diet

Abnormal Bird Droppings:

1. Increased size

2. Oily, bulky

3. Discoloured to a shade of green. Any colour from khaki to forest green.

4. Are often wet.

5. Carry a smell.

so I'm a little confused. Green good or bad?
