Broiler chicks require broiler starter feed for the first four weeks of their life. The broiler starter feed should be at least 20 percent protein, preferably 23 percent protein. After four weeks, you should feed a 19 percent protein feed (broiler developer or finisher). Commercially prepared broiler starter, grower, and finisher. Use a coccidiostat in the starter and grower. Follow your feed supplier's or veterinarian's recommendation for coccidiostat in the finisher. A broiler chicken will eat about 1 kg of starter, 1.5 kg of grower and 1.5 kg of finisher to reach market weight.
