Evidence of laws banning chick culling, and of notable legislative activity in countries without a ban, has been gathered from official sources for each country. Some of those sources were extracted from a report by the European Institute for Animal Law & Policy: "Chick and Duckling Killing: Achieving an EU-Wide Prohibition" (White paper, updated December 2024) by Alice Di Concetto, Olivier Morice, Matthias Corion, Simão Santos.
Sources for the countries with a full or partial ban (the status and the year when the ban became, or will become, effective are given in the data):

Austria: Section 6(2a) of the Animal Welfare Act (§ 6 Abs. 2a Tierschutzgesetz). Chicks used for feed production are exempt.
Belgium: Walloon Government communiqué, 3 July 2025 (Communiqué du Gouvernement de Wallonie, 3 juillet 2025). Regional measures only: Wallonia banned the grinding of live chicks (a ban on gassing is under discussion), and Flanders approved a ban on killing day-old chicks in its Animal Welfare Code, which will only take effect on a date yet to be decided.
France: Article R 214-17(II) of the Rural Code (Article R 214-17(II) du Code rural et de la pêche maritime). Chicks used for animal feed are exempt.
Germany: Section 4c of the Animal Welfare Act (§ 4c Tierschutzgesetz).
Italy: Legislative Decree 205/2023 (Decreto Legislativo 7 dicembre 2023, n. 205). Implementing guidelines on in-ovo sexing were published in September 2025.
Luxembourg: Article 12(13) of the Law of 27 June 2018 on animal protection (Loi du 27 juin 2018 sur la protection des animaux). General prohibition on killing animals for purely economic reasons.
Switzerland: Article 20(g) of the Animal Protection Ordinance (Art. 20 Bst. g Tierschutzverordnung). Shredding of live chicks is banned, and destroying embryos from day 13 of incubation is also banned since February 2025, but killing hatched chicks by gas remains legal.

Countries without a ban, but with formal initiatives or discussions about ending chick culling:

European Union: EU Livestock Strategy, European Commission (COM(2026) 576 final). The European Commission intends to propose, by the end of 2026, a revision of animal welfare rules for laying hens and broilers that includes ending the systematic killing of male chicks.
Brazil: Bill PL 783/2024, Chamber of Deputies of Brazil (Projeto de Lei 783/2024, Câmara dos Deputados). A bill to ban the cruel disposal of chicks is under discussion in Congress.
Netherlands: Parliamentary letter on the chick culling roadmap, Dutch Government (Kamerbrief aanbieden roadmap eendagshaantjes). A voluntary agreement between the government and the egg sector phases out the culling of male chicks for table-egg production from 2026, but it is not legally binding.
Norway: Parliamentary recommendation on the animal welfare white paper (Innst. 200 S (2024-2025), Stortinget). A parliamentary proposal to ban chick culling was rejected in 2025; the industry pledged to adopt in-ovo sexing by July 2027.
United Kingdom: The Welfare of Animals at the Time of Killing (England) Regulations 2015 (WATOK). The government's 2025 animal welfare strategy encourages the industry to end chick culling, but has no legal force.

All other countries are shown as not banned: no law against chick culling is known there. For European Union countries, this is confirmed (as of December 2024) by the report above.
