Difference between broiler houses and a layer houses
Layer houses are generally wider and higher than broiler houses. The poultry curtains are also larger – the opening allows more ventilation for caged hens. This is too easily allow the litter to dry underneath the battery cages ( the dung falls through the cages and falls on the floor – while slaughter birds live on shavings which absorbs the dung). Broiler houses do not have layer cages or nest boxes whilst layer houses do (broilers do not lay eggs – so no need). The laying house is for hens to produce eggs over a 60 week period, the broiler house is to bring up baby chicks for the purpose of eating, and they will be in the structure for 5 weeks to 6 weeks. The structures are very similar – but the poultry equipment used is very different. Watering tanks and curtains are the same – although the curtains are sometimes bigger in laying structures. On a layer farm items like egg sorting machines and refrigeration are required.
The chicken feed you give hens is also different to the poultry feed you would give to slaughter birds. The basics of caring for them is the same though – plenty of water, food, warmth or coolness and protection from predators. The disease challenges are similar and the medication, vitamins and Vaccinations follow the same principles. Poultry diseases like avian flu virus and coccidial infections affect all birds.
Poultry diseases in South Africa
- FOWL POX
- INFECTIOUS BRONCHITIS
- INFECTIOUS LARYNGOTRACHEITIS
- MAREKS DISEASE
- NEWCASTLE DISEASE
The above chicken diseases plague all chickens all over the world. Some of the medication is given through the water system – and other kinds need to be administered to each chick or hen individually. The two types of farming should never be practised in the same coop, or even in near proximity to each other. In large commercial farming these two types are never practised on the same farm, but miles apart. This is because disease from one will kill birds from the other – remember one deals with babies (very susceptible to disease), while the other deals with adult birds.
The higher layer house is so that tiered layer cages will not be too close to the roof, while the extra width is so that you can maneuver an egg trolley around the layer cages when collecting the chicken eggs. A 30m x 7m layer house will accommodate 1760 (if you place 5 birds per segment) or 2464 (if you place 7 birds per segment – too many in my opinion) – A 30m x 6m broiler house will house 2700 broiler chickens. A 9m x 7m layer house will accommodate 240 hens (if you place 5 birds per segment ) or 336 hens (if you place 7 birds per segment) and a broiler house of the similar size will house 810 chickens. What is a layer? – a layer is a hen that is bred for producing eggs. What is a broiler? - a broiler is a chicken that is bred for slaughter – for it’s meat. If you are raising the hens on the floor of the coop you would use nesting boxes for the hens to lay eggs in, and the number of birds you can have per drinker or feeder is less than that in a broiler farm house. This is because the birds are much larger when they are raised for egg farming (they are alive for so much longer and therefore grow bigger – this means less birds can fit around the drinking equipment and feeding equipment.
