How well known is chick culling among US consumers?

The lifespan of a male chick on a laying hen hatchery is just only one day. Shocking but true and sadly also a littleknown one among consumers in the US. In an article from Altals Obscura, John Brunnquell, founder and CEO of free-range egg producer Egg Innovations and Robert Yaman of Innovate Animal Ag, point out the differences between the European and US markets. According to a 2023 survey, only 11% of US consumers were aware of the practices of chick culling, even thought around 300 millions of day-old male chicks are culled every year in US. After being informed, 73 % felt that the industry should find solution to end chick culling.

7 March 2024

What are consumers’ perceptions of animal welfare?

The latest survey by the consumer organisation @BEUC highlights how European consumers value animal welfare in agriculture. The results from 8 Member States show that chicks and pigs are perceived as the animals with the worst husbandry conditions. Shockingly, many consumers – 29% of respondents – remain unaware of practices such as chick culling, where millions of day-old male chicks are culled every year. This underlines the need for greater awareness and harmonised legislation in all Member States to ensure consistent animal welfare standards.

Germany shows how quickly a market can change!

Not only was chick culling ended within 2 years. The solution behind it has also changed completely! In 2022, the main solution with 70% was brother layer fattening and in 2023 everything has turned around! 70% of laying hens “Free of Chick Culling” came from in-ovo sexing supply chains. Why is that? The capacities of in-ovo sexing were drastically increased (by us, among others) and the criticism of brother layer fattening became greater. For 2024 we expect an even larger share of in-ovo sexing!

28 February 2024

In-ovo sexing is reality

Culling day-old chicks is getting less and less accepted in the modern world. After all, the awareness of animal welfare is gaining ground, particularly in Europe. As the article by Avinews International points out, the introduction of technology to identify an egg’s gender during incubation is a breakthrough in animal welfare, eliminating the need for the controversial culling of male chicks. This ensures only female chicks, destined for egg production, are hatched, while male chicks are spared from being born and face immediate culling. This advancement not only addresses ethical concerns but also exemplifies the positive impact of technology in resolving longstanding issues in poultry farming, marking a significant step forward for the industry.

We are one step further in Norway!


For the very first time, laying hens that have hatched “Free of Chick Culling” are being housed into the laying hen farm. Soon they will start laying eggs, thus establishing a new standard: Ending chick culling in the egg shelve in Norway and Scandinavia! Congratulations to our partners Steinslands & Co AS and Nortura!

13 February 2024

Last night there was a culinary novelty in Norwegian star cuisine! Brother layer meat!

In order for an egg to really be produced “Free of Chick Culling”, the few male chicks (max. 2%) that still hatch after in-ovo sexing must not be killed! The Respeggt standard stipulates that the brother layers must be fattened for at least 10 weeks and at least up to 1.3 kg. After that, they must be used for human consumption. Our partners in Norway had a great idea for this! Steinsland & Co AS recently had the first slaughter of brother layers and was able to inspire none other than the Head Chef of the starred restaurant Vaaghals and captain of the Norwegian Olympic team: Christer Rodseth for preparing it. Yesterday evening, they dined like royalty together with the farmers who reared the brother layers. What a great experience!

Several high-end restaurants in Norway have shown interest in brother layers, this will be an interesting journey to follow.

Update on our new chapter at hatchery Weiss

Stepping into the new year with a bang! We are thrilled to announce that we’ve successfully completed the installation and setup phase of our modular, highly automated technology at hatchery Weiss in Germany. After rigorous testing and fine-tuning, everything passed with flying colours and our technology is now fully operational and ready for production.


27 December 2023

A new milestone was reached!

One of our latest hatch showed: 93% hatchability, more than 99% female chicks and an incredible number of 2,4 hatching eggs per female chick! Reaching such low numbers of hatching eggs needed for one female chicks shows that in-ovo sexing is not only a solution to end chick culling, it’s a solution to abolish manual sexing after hatch! What as great achievement to end 2023 on a very succefull note!

Test Station´s installation at Lohmann Deutschland

The setup of an additional Circuit and Sorter is almost finished! Additionally we are installing a brand new Test Station! Why?

Weser-Ems, Germany’s leading egg price index, switches to reporting eggs “Free of Chick Culling”.

We’re excited to share that during the recent Association of 𝗪𝗲𝘀𝗲𝗿-𝗘𝗺𝘀-𝗘𝗶𝗲𝗿𝗽𝗮𝗰𝗸𝘀𝘁𝗲𝗹𝗹𝗲𝗻 𝗲𝗩´s General Assembly of Members, they made a pivotal decision in line with the commitment to transparency and ethical practices in the poultry industry. From week 36, their quotation for German eggs will transition from Type 2 rearing (barn, KAT) to the more ethically sound barn eggs (KAT) “Free of Chick Culling” (Ohne Kükentöten – OKT eggs). The new standard will officially come into effect with the weekly list publication on 8th of September 2023. This will give the topic of ending chick culling a bigger platform and hopefully sets a new standard for the German egg market. We believe in leading by example and hope others will follow this path towards a more humane and transparent poultry industry.

16 June 2023

Change of German legislation

The Federal Ministry of Food and Agriculture (BMEL) modified the existing legal regulation regarding the culling of chicks in Germany. Up from the 1st of January 2024 in-ovo sexing can be performed until day 12 of the incubation process. The latest research done by the Technical University of Munich on how chicken embryos feel pain has been recognized. The legal framework for the legislation on chick culling in Germany now provides planning protection for the egg industry.

15 June 2023

Closing of Zeewolde hatchery

This week the last in-ovo sexing of our team took place at the hatchery Verbeek in Zeewolde, the Netherlands. The hatchery will be closed due to the location having a very high incidence of avian influenza.

We also want to thank the team of Verbeek for being one of the leaders in in-ovo sexing in the Netherlands and for trusting in our technology as one of the first hatcheries in 2021.
