I'm hoping someone will be able to help me here!
I had two zebra finches (one male and one female) but sadly, my poor little lady died. I didn't want the male to get lonely and didn't want lots of eggs (from past experience I know how much strain it puts on females) so bought another male. Unfortunately, they didn't see eye to eye and would often get into little fights. Feeling guilty that they were missing out on female company, we introduced another two female birds to the cage to calm them down.... This has worsened the problem!

They have formed little groups (1male and 1female in both) and the dominant two 'bully' the others. They're constantly fighting eachother, trying to show dominance etc and I'm really worried I'll come home from work and it has gone too far!
My boyfriend wants to introduce more zebra finches (possibly one or two more females) but I'm worried it's going to make it even worse. Does anyone have any similar past experiences where this has helped? Or any other advice? Of course, there is separating them but this will mean they can never be put back together.... And the dreaded 'catching' them! ( I never handle them, they are quite content in their huge cage).
Any help would be appreciated!
