Adding stuff to chicken nipple watering system

[victorb17]

I have a nipple watering system. They love it, I love it. The only thing that would be better is to be able to add stuff to the water through the system. Currently I have to use a separate bowl.

Does anyone use some sort of an Injector to add supplements / antibiotics to the watering system? Does it clog the nipples?

I have a fertilizer Injector for the irrigation, and I was thinking about something similar.

Thanks!
