2.3 lbs /chicken - week

 

15.7 lbs /(2.3 lbs/chicken-week) = 6.82 chicken- weeks   

     theat is ONE chicken for 6.82 weeks   or TWO chickens for 3.41 weeks.

 

59 chickens x 2.3 lbs/chicken-week x 4 weeks = 542.8 lbs needed  (assuming 4 weeks in a month)

He already has 15.7 lbs     542.8-15.7 = 527.1 add'l needed     

    527.1/15.7 =  33. 57 more bags ~~ 34 more bags

 

59 + 15 = 74 chickens

74 x 2.3 x 4 = 680.8  lbs needed for 74 chickens        680.8 - 15.7 =665.1 lbs needed ~~42.36 bags~~43 bags
