During the incubation process it’s mainly the female bird’s responsibility of keeping the eggs warm to help the chicks develop. The female has a brood patch which forms before the breeding season to cover the eggs. The patch will regulate the temperature to about 37°C. She will rotate regularly to make sure the heat is steadily distributed. This will recede eventually before the breeding season ends. Occasionally some male bird species will share the task of incubating the eggs but only for a short period as the female recovers.
Each chick inside the egg has a bill that features a hard tip called the egg-tooth, which helps them break out of the shell. The chick will frequently tap its bill against the shell until it begins to crack and eventually pushing its tiny head outside. Then using its body weight, it forces the shell to separate in half. The nestlings will hatch blind and helpless, so will instantly look for help and support of their mother and require food to build their strength since emerging from the eggshell. As the nestlings grow, they begin to lose the egg-tooth in as little as a few days, or even weeks depending on the species.
To help the birds feed their young, we’ve formulated a special Fledgling Mix which has everything they need to give them the perfect start in life. Sunflower Hearts are a good all year round feed and loved by most birds, making them a great choice for your feeders!
Please avoid feeding whole peanuts during Fledgling season, as the smaller birds can potentially choke on these. You could instead feed the foods mentioned above, or switch to Peanut Granules.
