Poultry rewards attention to detail more than almost any other enterprise on a farm. The difference between a flock that returns a profit and one that barely breaks even usually comes down to three things you control directly: the temperature you brood at, the efficiency with which birds convert feed, and whether the flock is properly vaccinated.
Get brooding right in the first three weeks
A day-old chick cannot regulate its own body temperature, so for the first weeks you are effectively its thermostat. Start the brooder at roughly 32 to 35 degrees Celsius at chick level, then reduce by about two to three degrees each week until you reach ambient temperature, usually around 21 degrees by week four or five.
Do not rely on the thermometer alone. The chicks themselves are the better guide. Evenly spread birds moving freely, eating and chirping softly means the temperature is right. Chicks huddled tightly under the heat source are cold. Birds panting with wings spread against the walls are too hot. A crowd pressed to one side indicates a draught, which chills chicks quickly and is a common hidden cause of early losses.
Prepare the brooder before the chicks arrive: pre-heat for several hours, lay clean dry litter to a depth of about five to ten centimetres, and have clean water available so birds drink within the first hour. Early feed and water intake sets the growth curve for the whole cycle. Provide enough drinker and feeder space that every bird can reach without competition, keep litter dry by fixing leaking drinkers promptly, and ensure ventilation that removes ammonia and moisture without creating a draught at bird level. Damp litter is the origin of much respiratory disease and footpad damage.
Manage feed conversion deliberately
Feed is generally around seventy per cent of the total cost of production, so small efficiency gains matter a great deal. Feed conversion ratio is simply the feed eaten divided by the weight gained, and a well-managed broiler flock on good-quality feed will typically land somewhere around 1.5 to 1.8 kilogrammes of feed per kilogramme of liveweight.
Feed the correct ration for the stage. Broilers move through starter, grower and finisher rations, and layers need a pullet ration before switching to a layer ration with its much higher calcium content as they approach point of lay, generally around eighteen to twenty weeks. Feeding a layer ration too early damages young kidneys; feeding a grower ration to birds in production produces thin shells.
Waste is the silent cost. Fill feeders only part way, adjust their height as birds grow so they eat rather than scratch feed onto the floor, and store bags off the ground in a dry, rodent-proof room. Never feed mouldy or caked feed, as the toxins involved suppress growth and immunity. Water matters as much as feed, since birds short of clean water eat less and grow slowly. Keep records of feed used and weights achieved, because you cannot improve a ratio you are not measuring.
The three vaccinations that protect a flock
Three diseases account for the majority of preventable poultry losses, and all three are controlled by routine vaccination.
Marek’s disease is normally vaccinated at the hatchery on the day of hatch, so when buying chicks confirm that this has been done. It cannot be corrected later on the farm.
Newcastle disease is the single most destructive poultry disease in much of the region and can wipe out an unprotected flock. Birds are vaccinated in the first week or two, boosted a few weeks later, and then kept on regular boosters, which is especially important for layers and for free-range flocks exposed to wild and neighbouring birds.
Infectious bursal disease, widely known as Gumboro, attacks the young bird’s immune system and leaves survivors vulnerable to everything else. It is typically given in the second week with a follow-up dose shortly afterwards.
Depending on your area and system, fowl pox and fowl typhoid vaccinations are commonly added, and this is worth discussing locally rather than assuming. Follow the exact schedule on the product, keep vaccines chilled from purchase to administration, use clean equipment, and vaccinate only healthy birds. Where vaccine is given in drinking water, withhold water briefly beforehand so birds drink the dose promptly, and never use chlorinated water, which inactivates it.
Basic biosecurity holds it all together
Keep age groups separate, restrict visitors to the poultry house, use a footbath at the entrance, control rodents and wild birds, and clean and rest the house thoroughly between batches. Isolate any new or returning birds before mixing them with the flock, and remove sick or dead birds promptly. Observe your birds at the same time each day; a drop in feed or water intake is usually the earliest warning you will get.
