for a good farm how many chicjen should i go as a beginner

Start with fifty to one hundred chickens. That is a safe beginner size for learning feed, brooding, and disease control without too much loss. If you want eggs, choose Giriraja, Vanaraja, or Gramapriya. If you want meat, go for Cobb or Ross broilers. Keep one clean shed, dry litter, and proper vaccination from day one. If you want, I can help you plan the flock size by your budget and shed space.
