Silkies are a great breed but, are notoriously difficult to sex before 4-5 mos. of age - and sometimes not till they crow or lay an egg. If you buy younger birds than that you can't be certain what sex they are. There is also a big difference in hatchery silkies, and those from a silkie breeder. BYC has several dedicated silkie threads, the longest running and my favorite is, "Silkie thread," put that in the search box and it will pop up. It's probably one of the best ways to learn about the silkie. Wish you luck with your search and Welcome to Backyard chickens.
