Spent grain from the brewers is just grain minus any sugars. It has 30-40% protein and the rest is fiber. I use fresh spent grain all the time my birds love it. Used with fresh greens and grains that are mostly carbs (hence cheap) it can make a great feed.
I am not looking for a boy
in fact we might sell these but mom likes them and cuddles with them so they stay for a little while.Its just super rare for me to hatch all girls... most times it a lot of boys!
Turkey starter has more protein then most chicken stuff... normally about 25-30% protein.
Whole grains do make a better feed but if your like me with no extra $, spent grain with a good mix of starch/carbs/oil grains, oyster shells and fresh greens makes a cheap well rounded feed.
Most spent grains can be gotten fresh from micro brewery's and cheap to free depending (free is normally to those who will pick up everything they have and every time they have it.)
What you want to do is make sure to follow the %'s......
% protein
% carbs
% minerals
% fat
% etc
(%'s depend on what your making it for)
I like the books I posted due to the fact that they post recipes as well as tell you what % this grain has vs that grain vs etc....
One thing you have to watch for is vitamin deficiencies mainly A and D's
Some of the books even have photos of what the birds will look like if they do have a deficiency
I use 1 bag layer mixed with brewers grain, starch/carb/oil grains, oyster shells, and alfalfa crumbles (run pellets through my apple grinder that is for cider)
Fresh Brewers grain is moist so I mix all dry stuff in a barrel and have the brewers in 5 gallon buckets. I scoop brewers then I scoop the dry and mix at each feeding.
I also mix in any left overs and then place in the feed trough.
Every 3 months or so I feed squashes cut in half seeds and all to the birds.
I have never had any problems with my birds having any deficiencies or being unhealthy nor have I ever had any mites, lice or bugs/worms of any kind. (they have a large dry area to dust bath in as well)
In fact I have a couple girls that are so fat they can't get on the roost any more. The 2 hens are large bodied and well.... piggies
So figure out what %'s you want to use for your flock then find the mix that will give you the right % making sure you cover the vitamins as well as everything else.
you funny!
