Such a good point that I'm sure is easily overlooked! Makes the cost of dried fish meal seem so much more economical. But I realize there are benefits to raw meat as well, enzymes, B vitamins, etc. I'd like to see if I can get my hands on a whole beef liver, chop it up and freeze it and feed it as a supplement to the birds.
I've seen your posts here on BYC several times and you seem to know your stuff around nutrition, thanks for sharing. Do you know the expected shelf life (once opened) of a bag of fish meal preserved with Naturox?
Yeah, I'll check on that about the fish meal. The fish in Scratch n Peck is Menhaden fish usually from off the Baja coast, which apparently has very little market as human fish food, but makes great feed. So I doubt it would be just the fish heads or skeletons, but if I do go that route, I'll be sure to double check. The link to the 50lbs bag of fish meal doesn't specify what species of fish is in it. Shipping any of this stuff is prohibitive for the average backyard chicken flock, unless you can get a group order or go through your local feed store to see if they can special order. Thanks for the tip.
