congrats pm the green cheek, they are great little birds and full of personality plus! we have 5 of them and they never stop amusing me. they are very demanding on time but so worth it, they are super sneaky but we have one that has worked out how to open a 2 latch door, my galah has not done that yet and he is pretty switched with things. have fun with him/her.
and not to get too involved with the whole seed, pellet, fresh thing .... too much anyhow, but as mentioned pellets have come a very long way in the last 15 years, roudybush for example is an excellent food source and in JMO a far better food souce than seed and fresh, also as mentioned "seed is bad", mind you too much fresh is not so hot either, as some fresh doesnt have the right mix of vitimans required either, you dont see budgies in the wild eating carrot and celery all day, they pick seeds, bugs etc etc, ssssooooo prepaired foods like roudybush have been developed since about 1981, i think, to be a great all round processed and clean consistant food source, people like "brisbane bird vets" (who is very well respected in bird and vet circles in general) would not sell and reccomend it, for example if it was no good, and i say this comming from not a crazy bird breeder (not saying bird breeders are crazy mind you
) but a vet nurse of 10 years (and my wife for 9 years) and a bird keeper and pet shop owner as well.
so yes plenty of people feed seeds only, mostly due to poor knowledge, some do seeds and fresh, and some do good quality pellets also.
out of intrest when feeding roudybush (as this brand was mentined) there is no need to use grit or cuttlebones or other additives as you need to add to seed and fresh diet as the pellets already have these covered into their consistant balanced formulas, pretty neat right? (dont beleive check the roudybush web page for more information)
anyhow good luck withthe new family member
cheers
