6 Down To 5 Budgies And Ones Not Fitting In.

Hi
Recently I have had one of my female die while I was on holiday so my even number (3M 3F) has changed (3M 2F) . Both my other hens have gone into season so I have had to split the cages. 
The problem is my oldest Male (my rescue so he's not tame) is not fitting in in either cage. 
Cage 1 he's ignored and looks lonely. 
Cage 2 he is chased by the other male. 

I'm not sure what cage is best. 

Thank you for any help you can give me.
