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?

You should be able to get save a chick probiotic in your feed store or tractor suply it goes in there water.

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.
