Granny, for my chickens, I crack corn with my chipper/shredder - I can do probably a ton per hour with it.<<<
Thank you for the good information on the mills.
We had Mary and Jay’s cornmeal grinder, from their flour mill in Yuma in the 1920, and Bill rigged it so the pully and a canvas strap would turn it, using the wheel drum of an old Studebaker pickup, that he jacked up and it worked for years.
We make coarse grind for the baby poultry feeds and even for the others.
Good when soaked in goat milk.
A couple of things to remember in making your own poultry - or any livestock feed -
Protein levels need to be optimized.
Soy Beans are an excellent source of protein (but they MUST be roasted first - kills the enzyme that is detrimental to livestock)
Rule of 4 for achieving desired protein levels:
Draw a square and write the desired protein level you want in the middle... On the top left, write one of the ingredients and under it put its protein level, put the second ingredient and its protein level on the right. Now subtract the center value from each ingredient and put it in the opposite corner (forget the negative amounts.) The results are the number of pounds of each you need to make the target protein percentage.
Corn________ Soy Beans
9%........................42%
............23
19#.......................14#
So, Corn at 9% and Beans at 42% you need 19# corn and 14# of soy beans to get a 23% ration. (ignore the periods - they are just to space it right)
So, since they total 33 pounds, you would need 57 2/3# corn and 42 1/3# soy beans to make 100 pounds.
Baby chicks need about 23% protein
Layers only need about 14%.
