In normal hatchery practice, eggs are transferred from setter trays to hatcher baskets at day 18–19 of incubation. It is important that these hatcher baskets are properly cleaned, disinfected and dried to ensure a hygienic start for the new-born chicks. Starting the hatch period with wet baskets will cause a temperature drop due to the energy needed to evaporate the remaining water, which will delay the hatch, widen the hatch window and negatively affect chick quality.
It is not uncommon to see these basic conditions not being met. The reasons for this are:
In situations like this, not only are the hatch results compromised, but increased first week mortality can also be expected.
The best way to address these issues is to tackle the root cause and optimize the washing, disinfecting and drying process, and perhaps invest in an extra set of hatcher baskets.
Some hatcheries choose to keep the hatcher baskets clean during the hatching process by lining them with paper prior to transfer. While this does not remove the need to wash the baskets after a hatch, it will be much easier to clean them properly, which is essential for successful disinfection. Another valid reason for applying paper would be to deal with batches of eggs with a higher number of potential ‘exploders’, as the paper prevents the bacteria-loaded mess from dripping into the baskets below.
