Kalmbach layer is all I use... and have used for years, except for the chick starter to ward off coccidiosis during the wet months.In a nutshell, yes. Good essential amino acid and fat-soluble vitamin numbers
At least as important is freshness. Always check the mill date before buying. Less common feeds like this are sometimes left on the shelf unsold longer than they should.
The crude protein may be a little too high for constant feeding.
Thanks for mentioning the "Mill Date". Didn't know about that.
Kalmbach is local to me. Sandusky Ohio.
