I am going to suggest MyPetChicken.com that is were I got my from and they are all happy and healthy chicks. I was very happy with them and there customer service. You can order as few as 3 chicks that are a standard size and if you want bantams then you can order 5 I think it is. They also had some red star pullets that are 20 weeks old that you could by last time I looked. I don't know if they have them all of the time but you could call. They sex them and vaccinate them if want that is extra. When they say pullet they mean an actual pullet. The rest of the time they say female or male.
