Sir Nemo, I think 8 php per bird is too small considering the amount that you´ll spend in rearing them chickens.... LPG for the heaters 24 hrs a day for 2 weeks, current, medicines and wage for the care taker roughly you´ll spend around 25k ..dont forget you´ll need to have money for the maintenance of the housing since this will not last forever, but if it´s true that its the amount that they will pay you then I think this bussiness is not profitable...coz you can´t raise them all and some will be rejects that will not pass that standard weight..this is just my calculations on a 5,000 chicks, anyways these are just my thoughts no offense meant Sir, just want to write down my opinion
