I found this in my layers feed

Now I buy feed weekly from a farm that makes their own feed and the stuff is amazing. But I found like 7 of these in a bag. Now I keep my bags super secure and tied up in the shade, no humidity etc. I reached out to the em ur they never got back to me. What could it be. It's crunchy and hard

Could be anything, but kinda looks like charcoal.

Looks like a vitamin wad or charcoal
