Sharon Gravelle, 62, served 2 years on child abuse and endangering charges. Her husband, Michael Gravelle, 62, is scheduled to be released Monday.
The couple lost custody of the children in 2006. The Gravelles said they used wire and wood enclosures at their home in Norwalk in northern Ohio to protect children they said were unruly and destructive.
The children, who suffered from problems such as fetal alcohol syndrome and a disorder that involves eating nonfood items, ranged in age from 1 to 14 when authorities removed them from the home.
