Mine came from mypetchicken...but you can also order small quantities from other sites, I think Ideal is one of them! Also many of the farm stores will soon be carrying chicks around here. Agway, and Tractor Supply will have them in my neck of the woods! The flat panel heater and the thermo cube are 2 separate items, I bought them both of the internet...amazon.com. My husband ran an electrical line to the coop rather than a extension cord.
