Does the nestling behavior change before they fledge the nest?
The baby canary does go through a behavior change when they reach 14 days old. They become wary of movements and noise in their surroundings. The flight instinct takes over when they feel threatened and will feel the need to escape to safety. A thorough cleaning of the cage when the babies reach 12 days old will prevent you from disturbing them when this behavior is reached. This will help them to fledge naturally.
