You actually have two male zebra finches, (Taeniopygia guttata), not society finches (Lonchura striata domestica). This is a much more aggressive type of finch and you must watch for aggression as I have had male pairs of zebras try to kill one another after several months of peaceful cohabitating. They can become especially territorial if they have a nest in their cage so actually, I recommend removing that. Even if they sleep in it together for now, one may claim it later and decide not to share. It can be cleaned by soaking in warm water for a bit then scrubbed with a cloth or a brush.
If you're lucky, you will have a true bonded pair and they won't fight, and you can let them have a nest, but if you see any chasing whatsoever and especially if anyone pulls anyone else's feathers you should seperate them.
Omg!!!! Thank you!!! I took it out this morning when I woke up, they have sort of been not fighting but bickering over it I think, no feather pulling but they get a little cranky towards each other at least once a day and it seems to stem from the nest, seriously, thank you! I had no idea! Im not sure if the videos uploaded properly, I can see them on my computer but not on my phone so if I have to I’ll re add them after work today
