Hi there!
I went to their website. I buy this brand due to the high amount of sunflower seed which is 21% protein.
I discovered other goodies in my scratch mix, too.
https://thevellagroup.com.au/product/item/free-range-scratch-mix/
I don't feed it as the staple. It's just breakfast starter or treat. They have high quality pellets available during the day and free range of an afternoon, under supervision.
That is the highest percent protein I have ever seen for a scratch mix.
When I look at the website, I find this:
"Grain mix with nutrient shortcut pellet containing essential nutrients required by Laying Hens. Can be fed as a treat and or on its own or...."
So that particular mixture is made in a way that it can be a complete feed. The ingredients include "Nutri-Pellet containing Canola & Soybean Meal..." So there are some other high protein ingredients too, not just the sunflower seeds.
I notice from the address of the company that it is in Australia. That may explain some of the differences.
I am in the USA, and so are several of the other people in this thread (OP is in Missouri, SourRoses is in Florida). Over here, "scratch" is a name for something that is absolutely NOT a complete feed. I do not know if there is a law requiring such labels, or if it is just a convention, but it is common enough that I don't think anyone with experience will expect a bag of "scratch" in a store in the USA to provide protein anywhere close to what a laying hen needs.
So I think we may be seeing a country-specific difference in how the words are used.
Examples of "scratch" in the USA:
https://www.walmart.com/ip/Healthy-Harvest-Scratch-Grain-Treat-for-Chickens-40-lb-Bag/875337627
Information on the page includes:
"Designed to be fed as a treat to meet your flock’s energy needs."
"Feed at no more than 10-15% of the diet."
"Not a complete feed, use as a treat only."
When I zoom in on the photo of the back of the bag, I see the protein is 8%

Despite costing 4 times as much as the one above, and despite saying it's a "protein rich" mixture, this one is 9% protein.
From a store with several options, several different price points of scratch:
https://www.tractorsupply.com/tsc/product/producers-pride-scratch-grain-50-lb
8% protein, cheapest
https://www.tractorsupply.com/tsc/product/purina-organic-scratch-grains-35-lb
7% protein, more than double the per-pound cost of the one above
https://www.tractorsupply.com/tsc/p...o-premium-scratch-with-herbs-10-lb-scratch-10
10% protein, 10 times the per-pound cost of the cheapest from this store
(The higher prices are mostly for products that are "organic" and/or "non gmo")
