What is this poop indicating?

Hello - have two geese that are always together, so not sure which one is doing this. Guessing is the male, who was recently in 7-day regimen of antibiotics for respiratory infection. However, it might be the female who is laying eggs and maybe having a repro issue?

Anyway, is a watery dark grey blackish poop. What is going on??? What do I need to do?

I'd provide a probiotic just in case the antibiotics have messed up the bacteria in his digestive tract.

So you don't think anything serious? What kind of probiotic would you recommend?

I see these types of poops from time to time. I have no idea why it happens. We jokingly refer to it as oil spill poo…

Have they by chance gotten into a burn pile? Mine like to raid the ashes for charcoal from time to time and it also turns their poo black.
