Ok for the sake of simplicity let's say your only going to grow barley for fodder and use it as the primary feed. (this is more about the process i am coming to these numbers by as opposed to the specific seed being used -- math was never my strong suit) I've found non GMO untreated barley for 24.99 for 48# plus shipping by ups ground delivery at a cost of 18.94 for a total cost of 43.93 If each pound of dry seed turns into 6 pounds worth of live plant fodder (some places say 7 lbs) than that equates to 48 x 6 = 288 pounds of feed per bag. Now if 288 pounds of feed costs 43.93 that would make the feed cost per pound 43.93 / 288 pounds = 0.1525347222222222 cents If a large breed chicken on average has a live weight of 7 pounds and a chicken requires 3% of its body weight in fodder that means the chicken would require 7 x 3% = .21 pounds of fodder per day (plus grit and calcium supplement) but for the sake of convenience we'll round that up to 1/4 pound of fodder per day. And if Fodder per pound costs 0.15 cents than 0.15 / 4 = 0.0375 cents per quarter pound. Which translates into (minus supplemental grit and calcium) to 0.0375 x 365 days a year =$13.6875 annual food cost to feed 1 single chicken. If that chicken gives you 150 eggs a year 13.6875 / 150 eggs = a cost of 0.09125 an egg for a total cost of $ 1.095 a dozen Is that correct? This would mean you could feed 3.2 chickens for a full year off this one bag Can you really feed a chicken for 13 dollars a year? (of course im not factoring in other expenses which would jump of the price some) To me it, if my math is correct, this would be a no brainer to choose. If my math is horribly off I apologize to anyone who may have gotten excited about the prospect i presented.
