Often, owners of spectacled parrotlets will clip the flight feathers as a safety precaution for the bird. Typically, the first six primaries are cut. These feathers grow back when the bird molts (roughly twice a year). Nails should be clipped every four months to prevent overgrowth and ensure comfortable perching.
Forced molting typically involves the removal of food and/or water from poultry for an extended period of time to reinvigorate egg-laying. Forced molting, sometimes known as induced molting, is the practice by some poultry industries of artificially provoking a flock to molt simultaneously, typically by withdrawing food for 7–14 days and sometimes also withdrawing water for an extended period.
