- 1Brooding layer chicks (0 to 5 weeks)A brown layer produces for about a year and a half, but everything starts in the first five weeks. A chick that was cold, drank badly or was crowded falls behind and finds it hard to catch up. This lesson prepares the house, the arrival and the first weight, feed and lighting benchmarks.9 min read · 5-question quiz
- 2Rearing the pullet (6 to 18 weeks)Between 6 and 18 weeks, the pullet does not lay yet: it costs feed and work. Yet this is where laying is decided. A pullet at the right weight and well uniform at 18 weeks will lay longer and more steadily. This lesson teaches you to weigh, compare with the table and correct in time.10 min read · 5-question quiz
- 3Lighting in a hot climate: the programme week by weekFor a layer, light is a switch. You reduce it during rearing to let the pullet grow, then increase it to start laying. Two rules are not negotiable: never increase the light before the pullets have the right weight, and never reduce it during laying.9 min read · 5-question quiz
- 4Coming into lay (16 to 25 weeks): the calendar not to missIn a few weeks, everything changes: new house, new feed, rising light, first eggs. According to the strain targets, laying goes from 15% at 20 weeks to over 94% at 25 weeks. Each step has its date and its weight: this lesson puts them in order.10 min read · 5-question quiz
- 5Following the laying curve (25 to 80 weeks)After coming into lay comes the long production period. The strain table gives targets obtained in very good conditions; in an open-sided house, in strong heat, average laying over the year is often lower, around 75%. The key is not to copy the table, but to follow your own curve every week so you can react quickly when it drops.10 min read · 5-question quiz
- 6Water, heat, health and depopulation: holding laying to the endIn Côte d’Ivoire, heat is the layer’s first enemy, and water is her first defence. A hen that drinks well holds her laying rate and the strength of her shells. This lesson sets up water, the house against heat, health and biosecurity, then the depopulation that ends the flock.10 min read · 5-question quiz
- 7Egg quality: from the hen to the trayAn egg is sold first on its shell: clean, whole, strong, and the right size. This quality cannot be recovered after collection; it is built every day on the farm: layer feed and cool water for the shell, clean nest boxes for cleanliness, frequent collection and cool storage for freshness. This lesson follows the egg from the nest box to the tray.10 min read · 5-question quiz
- 8Cages or floor: equipping the laying houseOn the floor on litter or in cages: both systems exist in Côte d’Ivoire, and each has its own demands. The right choice is not your neighbour’s; it is the one you will be able to manage every day, with your house, your budget and your team. This lesson compares the two systems, then explains how to equip the house: nest boxes, perches, litter, feeders, drinkers and density.10 min read · 5-question quiz
- 9Reading your laying record sheet: spotting a problem earlyEggs, deaths, feed, water: four figures recorded every day are enough to see a problem coming before it becomes expensive. They still have to be recorded correctly and, above all, read together. This lesson builds the laying record sheet, gives the simple calculations and trains you on four practical cases.12 min read · 5-question quiz
- 10Moulting, feather pecking and cannibalism: prevention is better than cureHens losing their feathers and stopping laying, hens pecking each other until they bleed, eggs eaten in the nest boxes: these problems cost eggs and hens. They almost always have a cause in the way the flock is managed: lighting, density, feed, water, heat, collection. This lesson teaches you to recognise them and, above all, to prevent them.10 min read · 5-question quiz
