Thank you all so much for the responses and advice! Ok i think i will give this Zupreem a try, as im not that rich and this sounds like a healthy alternative.
Just out of interest, is it ok to mix two different types of pellet? Say for example the Zupreem and Harrisons? Or is this pointless?
I am going to try to order some Zupreem/Harrisons today online. Does anyone know a good website for this (i see most of you guys are based in the states so i may have to look for a UK based supplier), if not just an approximate price i should be paying?
Wendy Theon is doing great!

thanks for asking! Since the advice you guys gave me the other day i have bought him alot more toys in his cage, trying to make it abit more appealing to him, and he is now getting alot more comfy in there

often just goes and chills in there now and plays

The stepping up is proceeding well too, hes not yet doing it, but the other day he did step up, but as i pulled my arm away from the cage he franticly reached out backwards with his feet to try to find his cage again

i think it may be a bad idea to try stepping up training from his cage, so ive ordered an independant perch for him (still not arrived) hopefully this will make him a little more confident with it
He still goes mental when i leave for work thou xD hoping the more he sees i always come back the easier this will get.
I am still slightly concerned about his wing thou, he has one feather now that has sort of shrivelled or shrunk that pokes out, again probally just normal but as hes been on a mainly sunflower seed diet in the pet shop, i may actually post a pic of this just to be sure. Once he is confident with stepping up and just generally a little more comfy with me i will get him to a vet for a check up, but atm i feel i may loose all the trust ive gained if i stress him out with that.
Again Thank you all for your help and advice
