Cockatiel Kiko from chick to adult bird

Dear viewers and subscribers, in case you don't see English SUBTITLES in my videos, please activate the subtitle icon in the lower right corner of the video.
Cockatiel Kiko from baby to adult bird. Cockatiel Neo is often seen near Kiko, always ready to defend his chick if necessary.

Our cockatiels:
NEO - male, cinnamon (not normal grey ), hatched early 2019 and with us since June 2019.
DAISY - female, albino, probably hatched in 2019. She has been with us since 11/11/2019 and she is Neo's mate.
KIKO - male, whiteface, hatched at our home on 29/07/20. Neo and Daisy are Kiko's parents
