They do not need much. A Tablespoon or two each morning should do the trick.
Chickens do not digest milk products. The Pro biotics is what you want them to get from it.
Well, I finally got them to actually eat it instead of run around in it...They won't eat it from a bowl, but when I put it on my finger and stuck my hand in the brooder it turned into a feeding frenzy.
A tablespoon, for how many chicks? I have 16 in there right now.
