I found out about them when browsing a small farm's site. I live near the city, and the city folk are all wanting chickens but most can't have roosters. Since they are the bulk of my customer base, I want to focus on breeds that I think would do very well for the family with a small yard who just wants eggs. I love that the Jaerhons are auto-sexing, predator-savvy and excellent layers while requiring zero to little feed input if free-ranged, so I bought some hatching eggs. They are 6 weeks old now, and the boys have had their big, red, adult rooster combs already since 4 weeks!
