Synchro-Hatch™ narrows hatch window

Thanks to technologies currently available, the hatching process is steered by the biological developments of the embryo, with a narrow hatch window and better outcomes as a result. This article explains what happens during the hatching process and how Synchro-Hatch™ guides chicks through the hatch.

Hatch based on the biological stages of the hatching chick

Traditionally, hatchery managers controlled the hatching process, basing themselves on time schedules. Experienced hatchery managers achieved good outcomes, although these were not always consistent. Thanks to modern sensors and software, the hatching process is no longer based on timing, but on the biological signals emitted by the hatching chicks. This leads to better and more consistent results.

The stages of hatch

A technology that can listen to the biological stages and adapt the environment to the needs of the embryos during hatch is Synchro-Hatch™, a patented technology by Petersime. The starting point is to have a hatcher loaded with eggs with similar characteristics, which are incubated in very homogeneous single-stage machines. This results in a batch of embryos that are uniform and in the same biological stage.


Synchro-Hatch™ narrows the hatch window and improves chick quality

The results of working with new technologies are significant. Synchro-Hatch™ reduces the hatch window with four to six hours. The narrower the hatch window, the more uniform chicks are, enhancing both productivity and welfare.

Synchro-Hatch™ narrows the hatch window…

and leads to uniform chicks

Extensive in-house trials and research in commercial hatcheries show that day-old chicks

  • are significantly more uniform
  • are generally calm, but active and responsive when stimulated
  • have a stronger and more robust appearance
  • higher body weight
  • better feed conversion ratios
  • lower postnatal mortality rates
  • better efficiency in slaughterhouses
  • total higher meat output in the end


Synchro-Hatch™ lowers overall post-hatch mortality of chicks in farms

How does Synchro-Hatch™ work?

Synchro-Hatch™ gives the embryos the same signals and stimuli as it would experience from the attentive mother bird in nature and offers optimal hatching conditions. In nature, the parent bird does not sit back and watch the hatch happen. She intervenes and interacts during the entire process. During the hatching phase, she returns to the nest and sits on the eggs for the majority of the time to guide the chicks to hatch. This affects the rate of gas diffusion, the moisture exchange and the heat dissipation during the four stages of hatch.

Synchro-Hatch™ does not delay nor forces the hatch to occur. Correct is to say that Synchro-Hatch™ gives the encapsulated chick the same signals and stimuli and guides the chicks in the same way as it would naturally expect in the nest from the parent bird. It thus offers the optimal and most natural hatching conditions.

The technology uses two detection principles to detect the evolution of the hatch and how far the hatching has progressed:
