Hello everyone

CHICKS
- 1st chick: 25 days old (hatched on 14.06)

EGGS
unhatched (laid on 13.05 at 22:22 and 16.05 at 02:05)

Stork chicks grow exponentially. 90 days in the nest is like 18-21 years for humans. This means that 1 day in the nest is like almost 3 months for a human child. That is why their transformation is so amazing and fast.

In my opinion there are two factors, while they spend so few time on the nest (and Kerli is absent already more than 48 hour):

1. Migratory Urge and Time Constraints:
With the migration season approaching, the parents' internal biological clocks are ticking. Even though this chick is delayed (only 25 days old), the adults' instincts are already shifting toward their own pre-migratory preparation, leading them to minimise their time spent at the nest.

2. Feeding Basket Logistics and Time Management:
Although the feeding basket eliminates the need for long hunting trips, utilising it still requires specific timing and coordination. The parents must adapt their daily schedule to this artificial food source, prioritising food collection over returning to the nest and e.g. to shield the chick from the rain.
