Although forced molting of layers is a management practice dating back to 1905, it wasn't until the 1960's that commercial egg producers started to use it extensively as an alternative to all-pullet flocks. Current usage varies considerably within the U.S. Statistics (U.S.D.A.) show that on August 1, 1979, forced molted layers as percent of hens and pullets of laying age were 32 in the western states of California, Oregon and Washington compared to 8.8 in selected midwestern states.
