At stage 4, fledglings are engaging in advanced foraging education from other flock members and caregivers. Their weight is stabilizing with fewer assisted feedings. Fledglings are actively participating in primary lessons rather than just desensitization. Housing provides various perches, branches, and a mixed flight for more socialization and exercise. Primary lessons include reinforcement of commands on a scale and introducing a hair dryer after misting. Desensitization continues for sounds, towels, carriers and physical exams.
