They pick out the BOSS...and throw it on the ground

[fancy]

Did you say you feed it to your horses?

How young can your chickens start on BoSS?

 

[Organics North]

I make my own starter.. It contains boss.. So my birds have it with their first grain meal..

If you want to just throw it out whole, or sprout it I would say a couple weeks old.
Remember the grit!
