welcome ringneck newbi
in answer to your questions
1:there are alot of reasons both for and against clipping wings
i personally choose against it because of other pets we have (cats)
but others have clipped their wings & still had the mange to maover around fine
2:seeds a good start but they also need plenty of fruit & veges ther is a brilliiant post in diet & housing
keep away from onions mushrooms &avacado (all toxic to birds) look at the list of safe foods & playaround the birds will let you know their favourites
3: if its the cage they have always been in i cant see a problem if they have always been together they would probably want to stay that way
4:give them time. how long have you had them? they need to adjust to a new home &new faces put the cage where they can watch you when your not watching them eg; near computor or where you watch telly they will slowly come around talk to them & give them treats also eat in front of them (if they are out of the cage only bird friendly food as they are likely to try & pilfer it off you) for some reason eating seems to calm them
and might i also add your birds sound beautiful!!! can we see pics?
