I've only had two cups of coffee, I'm going to try and be polite.
I live in a very remote area. My internet is via cell phone. I have the best plan available (easy to say, when only a single carrier offers more than one bar service, WITH a powered antenna). I have neither the data bandwith, nor the time, to sit down and watch 30 minutes worth of videos in hopes of teasing a recipes from them when half the time my Facebook page loads as a banner and a screen full of white page...
Number ONE. " if I added things" - that's not a recipe. Well it is, but its a recipe for umnknowable chaos. "Ph'nglui mglw'nafh, Cthulhu R'lyeh wgah'nagl fhtagn!" Fixed it for you.
Number TWO. Salatins feed recipe is part of a system. You can't use the feed and expect good results if you don't use the System and understand the preconditions. That said, you can do worse.
Salatin has two recipes commonly offered:
52 Corn
29 Soy Beans (rosted of course, NOT meal)
11 Whole Crimped Oats
3.5 Fish Meal
3 Nutribalancer
1 Limestone
.5 Kelp Meal
.1 Probiotics
and
49.7 Corn
39.8 Roasted Sobeans
10.9 Whole Crimped Oats
5 Limestone (obviously a layer ration)
3 Nutribalancer
.5 Kelp Meal
Number THREE. That's J Rhodes' recipe, and J Rhodes channel, which I've already recommended as a good place to start. If all you are doing is throwing Youtube videos at me, waiting on me to do the real work for you, my TIME is worth much more than that. Running a calculator is simply not that entertaining to me.
Number FOUR
After adjusting for moisture content, and with the usual caveats about using averages, the eBay recipe is sub 16% protein, 6.5% fiber, 8.5% fat (2x to 3x too much), Borderline on Met, low to borderline on Lysine, Low on Threonine, and adequate Tryptophan. Those ingredients are NOT cheap.
Number FIVE
I'm not looking up their layer mash from a post 13 years ago, which if I recall correctly is a low protein scratch grain mix, so that I can calculate that before adding in more low protein, high fat corn, plus high fat sunflower, millet, and flax (the last three of which aren't cheap) so I can report on yet another high fat home brew feed mix which doesn't cut your costs any.
Number SIX
I looked at this yesterday.
IN THIS VERY THREAD
I think I have been EXCEEDINGLY patient. Now, because I'm not wired for "touchy-feely", I'll say this once for the audience in back. Your birds depend upon you for their diet.
Their lives are your responsibility. Either take responsibility and do the real work of doing your own research, or stick to commercial feeds. I have done the research. I have attepted to save time and effort by repeatedly stating that home brew recipes almost never provide balanced and complete nutritional needs and are almost always more expensive than an off the shelf commercial soluiton, and further, that the more I know about feeding birds, the less likely I am to attempt it at home.
For your own good, and for your bird's health,
we're done. Maybe I reconsider if I see some evidence of effort on your part - but thus far, I've seen less effort than I put into this response. I can only assume you are very young, and will hopefully gain maturity in the fullness of time.
