Its time to buy some more feed so ive been pouring over some records and comparing to some other sources. Another source i recently read stated a non-laying chicken would consume 60lbs of freed a year. and a laying bird nearly 90lbs. As all my birds arnt laying i used an avg of 80lbs/yr based on the above and did some calcs based on 50 chickens (that i have ish) so ~10-11lbs per day or 6.6 (50# bags) per month I then went back to my own records and compared what i had actually used for how many chickens. durring the first 9 weeks of the year (winter time when feed usage is highest) i used 300lbs in 9 weeks for 24 laying birds. or 1.38 lbs per bird per day or 69lbs per week. compare that with the book numbers and its almost exactly the same as the book numbers. today's feed price for 50/lbs of pellitized (i prefer pellittized) 16% layer feed at farm n fleet was $13.50. that price works out to $1080 a year in feed for 50 chickens. at $3 per doz eggs i have to collect roughly 360 doz eggs per year or roughly a doz eggs a day from 50 chickens to cover the cost of food.
