Feeding (Food, Water and Medicines/Vitamins) of 45 Days Old Chicks

Feeds (Crumble) and Water mixed with Antibacterial / Vitamin supplements

Feeding Ration 

Day 1 - 10 days old:  Feed your chicken with chicks booster rather than chicks starter. 

Days 11 - 42 days old:  Feed your chicken with chicks crumble.

Days 43 - slaughter:  Feed your chicken with finisher mass.

I suggest not to do any experimentation on your chicken feeds - the feeds that you bought in an agrivet shop has a complete nutrition your chickens needs. 

Water Consumption

Must use fresh and clean water, mix antibacterial and vitamins to your chicken daily drinking water if possible (as per veterinarian advised) - just a little amount to make the water yellowish in color.  Sometimes our tap water is not good since it contains chlorine and other chemicals that affects the chicken digestions, but its a rare case. 

Medication

If possible, don't provide your chickens with any medication if not required especially for broilers.
