My first and most important suggestion is to stop putting Ornacyn in her water and throw it away. I get so frustrated with pet stores that reportedly care about pets selling this potential lethal med that has never been known to actually make a positive difference for any bird.

Here's just a couple things to remember about it: Putting anything in a bird's water is more likely to put the bird off drinking (they think the water is fouled/bad) and cause dehydration. Dehyrdration in a bird is a serious, life threatening condition that can prove fatal after just a matter of hours.

Also, this med doesn't differentiate between 'good' bacteria and 'bad'. It will (if ingested) kill bacteria indiscriminantly. The 'good' bacteria is necessary for proper crop and digestive activity as well as a balanced, strong immune system. Results of no or low 'good' bacteria can end up costing people hundreds if not thousands of dollars to treat - and honestly, quite often it's not enough and the bird loses the battle anyway.

Finally, you're treating a bacterial infection by giving this med. If your bird has a virus or other condition, the med isn't doing anything but harm (in removing necessary bacteria or causing dehydration). Even if the condition is a bacterial infection, there are different antibiotics used to treat different infections and the only way to know which you're dealing with is through a proper culture/exam.

Now, in dealing with the changes you've seen, let's examine overall 'poopology' :

All bird droppings are made up of three parts: Faeces (feces), the solid, central part which can vary in color depending on the food the bird eats. Urates, the next layer of the ring, which can be cloudy-clear or with shades of white, yellows and greens, again depending on the foods eaten.

Urine is the clear liquid, usually outer layer of the ring. Depending on the amount of fruits and fluids the bird eats/drinks, this can be a significant part of the dropping.

Human companions to birds need to learn what's normal for their bird. When the bird is healthy, acting fine and eating a well balanced diet, there's a general look to the droppings that may vary depending on the time of day, but are usually similar looking.

If a bird eats beets one day, the droppings may look frighteningly reddish. Sometimes when the bird eats more dark leafy greens (or blueberries), the droppings can assume a nearly black hue.

When a bird is on a largely seed diet, the feces may be any shade of bright green; pelleted diets without added food colorings would produce a dull, brownish-green. If the bird is eating colored pellets, the droppings may reflect what colors are most often chosen.

Diarrhea is often actually Polyuria. True diarrhea is when the feces part of the droppings are not well formed and liquidy. Diarrhea is usually caused by a disease. Polyuria is when there's more than usual amounts of the urine and urates (the feces are still well formed).

Polyuria may be caused by viral infections, allergies to foods or even a tumor somewhere. There are just so many possible causes that a vet visit is essential in order to catch things early.

‘Bubbly' droppings are also considered abnormal. Some bacteria produce a gas and this is what may be causing the bubbles.

One day of abnormal droppings (usually appearing too loose or liquid) is not typically an emergency. As long as the bird is still eating, drinking and acting normally, there's no change in vocalizations, there is no feather fluffing (looking bigger), staying at the bottom of the cage or excessive sleeping - sometimes a change in droppings is little more than something that will last a few hours and be fine.

If there's ever red in the droppings and they have no dietary explanation, blood must be suspected and it's prudent to make an appointment with an avian vet.

If droppings remain abnormal more than 24 hours, please see a vet or have a mobile vet visit your home. It's far better to have a visit and exam find nothing wrong, than to miss something that with early treatment may insure the bird lives.

Some of the possible causes of abnormal droppings are liver/kidney disease, intestinal disorders or infections, food allergies, poisoning (such as zinc or other heavy metals), parasites, Psittacosis or even stress.

A vet should do a physical exam and may include any one or more of the following: Blood tests, gram stains/cultures, x-rays, even oral/crop/tracheal swabs and so on.
