Breeding goldfinches involves meticulous preparation. After ensuring the correct cage size, proper diet, and the introduction of nests and nesting materials, you need to know how to care for the eggs once they are laid. This guide will help you navigate this crucial phase of goldfinch breeding.
Laying Goldfinch Eggs
A female goldfinch typically lays 4 or 5, sometimes 6, bluish-white eggs with brown spots. She lays one egg per day and starts sitting on the nest after the last egg is laid. In the wild, the male goldfinch finds food to feed the hen and sings nearby. In captivity, the male behaves similarly.
Nesting Behavior
The hen leaves the nest a few times daily to defecate, preen, and bathe. During these short breaks, it’s essential to minimize disturbance. Cleaning should only be done when necessary to avoid disrupting the nesting process.
Handling Eggs
Handling eggs should be avoided as much as possible. If you must handle them, do so gently to prevent damage to the fragile shells. Many breeders swap real eggs with plastic ones as they are laid. This helps synchronize the hatching process, ensuring all chicks hatch at the same time.
Swapping Eggs
- Swapping Process: As each egg is laid, replace it with a plastic egg. Store the real eggs safely in a bowl with cotton wool or seeds.
- Returning Eggs: When the last egg is laid, replace all the plastic eggs with the real ones. This prevents chicks from hatching on different days, which could decrease the survival chances of the last chick hatched.
Monitoring Aggression
Keep an eye on the male goldfinch for signs of aggression during the egg-laying period. He might chase the female from the nest, damage the eggs, or pull the nest apart. If you notice any aggressive behavior, remove the male from the main cage. Use a wire divider if possible, allowing the birds to see each other without the male disturbing the nest. The female can care for the nest and newborn chicks alone, and the male can be reintroduced when the chicks are around 13 days old.
Conclusion
Breeding goldfinches and caring for their eggs requires careful attention and minimal intervention. By understanding their natural behaviors, providing a suitable environment, and handling the eggs with care, you can increase the chances of successfully raising healthy goldfinch chicks. Always observe your birds closely and adjust your approach based on their needs to ensure a smooth breeding process.
