Why weigh a sample?
As the sale approaches, the flock’s appearance is not always enough to estimate the chickens’ weight. Sample weighing gives a more reliable indication of growth and reveals differences between birds. It also helps you decide whether the flock is ready to be marketed or whether monitoring should continue.
Preparing for weighing
Choose a stable scale placed on a flat surface, and check that it displays zero correctly before you start. Have a suitable container ready if you are weighing the birds in it: first weigh the empty container, then subtract its weight, or use the tare function.
Avoid selecting only the largest or easiest-to-catch chickens. Take a representative sample from several places in the poultry house: near the feeders, drinkers and in different areas of the chicken coop. A sample of 30 to 50 birds may be practical for a typical flock; adapt it to the size of your poultry farm. Handle the birds calmly and return them to the flock promptly.
Weighing and recording the results
Weigh the birds individually, then record each result in a notebook or on your phone. Write down the date, the flock’s age, the number of birds weighed and the recorded weight. Calculate the average weight by adding the weights together and dividing the total by the number of birds weighed.
Then compare this result with the growth targets indicated for your chickens’ breed and age, as well as with the records from previous weeks. Also observe the spread: if several birds are noticeably lighter than the others, the average weight alone may conceal significant variation.
To compare weighings, keep the same conditions and time of day as far as possible. Do not withhold water or feed from the birds to weigh them. Note any recent change in flock management, such as a change in ration, high temperatures or less regular access to feeders, so you can interpret the results with caution.
Acting on your observations
If progress slows or weight differences widen, check the availability of feed and water, the space at the feeders and drinkers, and the conditions in the poultry house. If you notice unusual visible signs or have concerns about the condition of the flock, seek advice from the local veterinarian.
Before the sale, weigh a representative sample and record the results: this habit will help you make a decision based on observations rather than an impression. For your next flock in Côte d'Ivoire, choose a check date and keep your records up to date.
