..."Carriers" of several diseases
However...…using Society Finches as foster parents for Gouldian chicks is not without problems. While it is true that they have been bred over the years to be excellent parents, all Society Finches can become "carriers" of several diseases that will not affect them or their own offspring but could prove lethal to species of birds that have evolved in dry, arid conditions. The 2 most common "wet" diseases which Society Finches can carry, that will affect Gouldian chicks are Campylobacter and Cochlosoma.

I have found that while both diseases can be "kept in remission" during a breeding season to allow infected Society Finches to foster Gouldian chicks, I would not recommend doing it. By constantly medicating the Society Finches, you are also medicating the chicks. This constant medication does not allow the chicks to develop their own strong immune system and, therefore, the chicks produced will always be weak. I realize that this may put you between a rock and a hard place, should your Gouldian parents reject their chicks, but do we want to save them at the expense of their overall health for a lifetime? Also, many of the chicks that do survive will become carriers themselves and will then pass on this condition or passively kill their own chicks when they breed in later years.

To be on the safe side a veterinary diagnosis of the fecals should be done. It could be something totally simple like a mild bacterial infection.
Find out for sure before you start imagining and possibly treating for the worst.
Runny yellow poops could be a myriad of things.

Hope your birds feel better soon.
