I wouldn't stress or go further before I will give you a quick answer that it's the hatchery farm price, that's the manufacturers that determine the price that Broiler birds would be sold to the retailers and the final consumers.
Why it's the hatchery farm (manufacturers) that mostly determine the market price of Broiler birds.
Ordering day old broiler birds from the hatchery farm happens every week. Meanwhile, despite the supply happens every week, the price isn't fixed. The price of day broiler birds every is like a Lady who usually have mood swings every now and then. The last batch of birds I reared were brought with #750 per chick compare to the once I am reading presently that's just #340 per birds. You can see clearly the price range within that short period of time. So because of this, even the price for Broiler birds when they reach to harvest, I mean selling on kilo to the retailers or final consumers will have to change.
Why it's not the feeds sellers?
Feeds price also play a role in the price of Broiler birds but not as the major roles that hatchery manufacturers are playing in the marketing price of chicken product. This is because price of feed can be fixed or remains stagnant for a longer period of time. Even producer of broiler chicken like us do not have a say, we just have to dance to the tune that the hatchery farm price plays.
