Hi guys Ive had baby for about 10 days now he is about 13 weeks old and is doin fine and has settled in nicely now , guy in pet shop said to give him cockatiel mix with parrot mix but i noticed he flicks out all the small seed in cockatiel mix and only eats bigger seeds in parrot mix do u think it would be ok to just give him more parrot mix less cockatiel or does he need something thats in the smaller seeds

also he doesnt really touch any of the fruit or veg I give him he did at first then suddenly decided not to bother eating any of it

is there anything I can do to tempt him to eat his fruit and veg
