Thanks Ellie!
Good news all, I posted on my facebook page that I was looking for an aviary sized cage...Who said Facebook is all bad lol! My neighbour came running over saying he had a 1mx1m and 2m (ish) tall cage he was going to dump...So he gave it to me

It's in great condition. Bit of rust on the bottom frame but my boyfriend is going to help me tidy it all up so it's rust free and completely bird safe, before putting them in there. We're also Going to make a stand for it, so that I can flip it on the side instead so the IRN's can have 2m of flight spacce rather than 2m height.
Right now the cages are beside one another, no flirting but no fighting either, so that's a good sign! Will post photos soon of the cage
