If you head out I-90 to Issaquah, take the Front Street exit, turn left on Gilman Blvd and "The Grange" will be on your right. You can call them and confirm, but they have chicks almost all the time during the spring/early summer season. They will let you buy one or two (especially if they know you already have 1 or 2 - they usually recommend 3 for a starter flock).
