Aviahan pure bread

If you mean Avian, then pure breed birds are usually chosen for breeding and stable traits. For backyard use, Giriraja, Vanaraja, or Gramapriya are safer choices. For eggs, White Leghorn or BV-300 are better. For meat, Cobb or Ross broilers grow fast. If you want, I can help you pick the right bird for eggs, meat, or backyard rearing.
