I have 2 adult hens, how much should they be given per day or week?

Put a bowl or dish with it out for them. Hens are very in tune with their body and know when they need calcium. Refill as often as needed.

Is this too large for vermi-composting. Will worms eat it?

If worms eat oyster shell and calcium they would eat this, it's good quality rock.

Hi can i feed baby chiks?

You don't want to feed this to baby chicks. Only when they start laying eggs. Only feed medicated chick feed. You can add chick and grit later when there are about 8 weeks old. But do not mix the grit in with their feed. The oyster shell is to help with the calcium needed to create eggs. So do not give that until they are laying.

Where is this from USA ?

I can’t find anywhere on the package a country of origin. MannaPro is from St. Lewis, but the bag says manufactured for MannaPro.
