Chickens: how can I make mychickens to grow fasterand heavie?

[Henlus]

f u feed them well they will grow well. My last set of 49 broiler had the following schedule:

from wk0-4......2.5bags of starter

      ''          5.....36.8kg   of finisher

       ''          6.....45.6kg

       ''      7-8.....155.12kg  

the above give's a total of11 bags of feed to 8wks. And i sold birds weighing 2.4--3kg @ day 54 in the 8th wk. In ur case 11*2=22bags of feed  for 100 birds, don't believe in injection,if u feed them better u will have better results

I agree with you. There are injections that can be used to make them grow faster but I don't recommend such. They are not good for human health.
