You have used Bantam as if it were a specific breed of hen. Bantams are just smaller versions of a standard breed. Almost every breed of chicken is available in standard (large) or Bantam (small). On average a chicken will start to lay eggs at about 7 months old. Some breeds earlier, while other breeds mature later. The peak laying happens for about 18 months and then begins to drop. Most hens stop laying eggs at about 3 years old. See "related links" for breed descriptions and rate of lay.
Bantams, just like their standard size counterparts, lay at about 5 to 6 months old. It really depends on the breed of bantam you own as to whether they are good productive layers laying daily or slow layers who will drop an egg twice a week.
Depending on the breed, they start laying around when they turn a year old.

This is both an economic and health choice. Many small operations like to keep the birds on the chick formula/grower for up to 12 weeks. With Bantams, the larger size of the grain is sometimes a problem for small beaks and crops. As most breeds will not start to lay until they are 4 months old and older it is often a good choice to start the layer pellets in the 4th month.
