While we could see the hatching of the chicks in nest box no.1 on May 16, then the chicks in nest box no. 2 were hatched on the morning of May 18.
The just hatched chicks need to be kept warm during the first few days, so the female sits on the nest every now and then. The egg shells are partly thrown out of the nest but a part is eaten by the female to cover her calcium need. In their first days in life the chicks are fed the smallest invertebrates.
