These chicks are Easter Eggers - they are a cross between bantam Ameraucana (blue egg layers) and bantam Rhode Island Red (brown egg laying) birds. They will likely lay olive eggs, but could also lay blue or brown. Bantam chickens are smaller versions of the standard breeds. These chicks will only be 2-3 lbs when mature, and are content in a smaller space, so they are great for small backyards. Will be very friendly if handled from a young age, and are excellent layers of small sized eggs. Unsexed, although I can take roosters back if you are unable to keep them.
