- Stress on the Birds: Moving the house can cause unnecessary stress to the birds, which can impact their ability to incubate the eggs and care for the hatchlings.
- Egg Breakage: Moving the house may cause vibrations that can lead to egg breakage. Bluebird eggs are fragile and can easily be damaged or cracked during movement.
- Abandonment of the Nest: In some cases, moving the house can cause the birds to abandon the nest altogether, leaving the eggs exposed and vulnerable.
If you must move the house, it's recommended to wait until the eggs have hatched and the chicks have fledged (left the nest). If the eggs are close to hatching, you may consider carefully monitoring the house during the move and providing protection to minimize any potential risks to the eggs.
