爱亚卡普·汉斯&艾弗特-杨（eijerkamp hans & evert-jan）
Hans and Evert-Jan Eijerkamp's highly successful “grey strain” is largely based on the well-known Leideman pair “Viton” x “Daughter Goed Grijs”, and we are also talking about the classy “Speedy Grizzle” family.
Hans and Evert-Jan selected classy 2025 pigeons from the highly sought-after ‘grey strain’ especially for Pigeon Bids.
