EDIT: found it!!! Thank you so much!!! here it is
*It's a pop childish/for children song, in french, sung by a woman but edited to be kinda robotic;
*It features a pink chicken-like creature, it's either a cartoon or a 3d animation (i don't remember) and it ends with characters watching sunset;
*It was on serbian 'kanal D' tv channel about 10 years ago, so i'm guessing it's a bit older than that. I was around 6-7 years old so I don't know any of the lyrics, other that it contains word 'blanche';
*I know the mellody but neither shazam and other apps nor online voice recognition sites don't recognise it;
Please if you know anything about the song help us, my friend and I are desperately looking for it.
