I have posted on the high cost of feed before,,and if you grind and mix your own feed,it can be done for 1/2 of what you pay for commercial bagged feed.Common knowledge is notice the selling price of what corn is selling for daily on the Chicago Board of Trade,,last I knew a few days ago,it was selling for $3.75 a bushel,,56 pounds worth,,dried to 15.5% moisture,,,2/3 of poultry feed is corn based with a protein value of 8-9%,,you can then easily use the Pearson Square method to formulate any desired protein level of feed to be made,,as long as you know what the protein levels are in the ingredients your wanting to use.
I can buy a 40 pound bag of cracked corn for $7.84,,a 100lbs of Hubbard poultry developer for $23.00,,or a 40 pound bag of Nutrena chick starter for $8.75 a bag (both 16% protein levels) Because what was once a hobby has now turned into a cash cow for feed costs each week, I purchased a corn-roller crimper,that will crack or grind corn down to flour if you set the rollers tight enough. It is powered by a 9 hp Honda engine,,and you can crush,or crack a 5 gallon bucket of corn in less than a minute with this.I plan to mount on a frame and add two poly cone bottom bulk bins,a few augers,and then be able to grind,mix,and either store or unload the mix.It will be like a mini feed grinder,all done for less than $2500,,,
There are advantages and disadvantages to this,,but with feed cost the major factor in any livestock-poultry operation,,with the number now and intended number of chickens and poultry I plan to have,I can easily justify the initial cost of making my own grinder mixer,and paying for itself in less than 6 months time.
