Probiotics aren't just for humans :-)

I've had great success using probiotics for various ailments in my backyard chickens and I made a video showing how they helped a badly battered rescue chicken.

Nice video

I use a probiotic powder formulated specifically for chickens.

I use it in chicks first water.
I also use it and a bit of Kefir in my fermented feed.

Chicks with a healthy mother hen get probiotics from some of her feces.

Right from the start is best with humans so it makes sense that it would be with chicks too.
