So here is my math...but I may be way off on my estimates:
1. I think I have ~30 chickens (when you have that many and they are the kids...you really stop trying to count and just say "I have too many".) I just buy the food when they are low so the following are guestimates on my current usage:
A. Currently:
(3) bags of 50 lb feed/mnth @$15/bag = $45
(2) bags 50 lb cracked corn @ $9/bag = $18 (kids prob over feed this, but it is what it is)
Total: $63/month in feed
B. Estimate with fermenting feed and fodder
I bought the following yesterday:
(2) 50lb barley @ $13/bag
(2) 50 lb wheat @ $13/bag
(1) 25 lb sunflower seeds @ $15/bag
Total is 250 lbs seeds x 6 (estimate on weight gain with fodder) = 1500 lbs green food/$67 spent = $0.044/lb of food
So to feed my 30 piggy chickens: (fig 2 lbs per each in food per week)
(2) bags of 50 lb feed/mnth @$15/bag = $30
30x1lb fodder x 4 weeks = 120 lbs fodder/month @ $0.044/lb = $5.28
So hopefully $35.28/mnth which is about 50% savings. As to if that will really happen...will find out this next few months
