Now that spring is almost here, several of our local feed stores are carrying various breeds of baby chicks, such as Barred Rocks, Brown Leghorns, Austrolorps, Rhode Island Reds, etc. All the chicks are less than 2 weeks old and some are less than a week old. Yet the feed store manager told me today that although the occasional cockerel gets mixed in, all the chicks they carry for sale are female, and he also said that the hatchery where they buy their chicks each spring is able to sex breeds such as the one I've listed as early as one or two days old. How is this possible? It's my understanding that woth the exception of sex-link varieties, there's no good way to sex a baby chick. Am I missing something here? Thanks!
