Male budgies(3yr old)cere has turned a bit crusty and brown

[aesteticar]

Ive had him for about 3 years and he has always shown normal behaviour. He eats well, flies a lot, drinks well etc. Two weeks ago ive noticed that his cere has changed its appearance. He is still very lively and hasnt changed his daily routines and overall joy! He eats two types of different food, millet and has sand as his floor which has crystals in it, plus he has a crystal tray to eat too and a squid bone! In my town of Belgrade there are not many avian vets or vets that care for budgies, plus i dont want to stress my buddy out with unecessary vet visits that are not able to diagnose him properly so thats why i come to you guys! What do you think this is, is it just dry skin is it just a bit of hormones is it iodine deficency what do you think? Any comments will be more than helpful. Thank you all in advance <3

I thin’ this is most likely dry skin over the cere. Perhaps a misting would encourage him to rub his face on his perches, it may help rub some off.
