Answer
Hi yes seperate them all thats a total of six different cages differnet light and heat setups also. Dragons shouldnt be housed together regardless of there sex/age they do fight and or breed each other to death. The little one needs a vet right now he may have internal injurys from the fight or a fratured skull or something he might need to be put down if the vet suspects he is in alot of pain for skull injurys please take him to the vet right away. sorry I can't help more I'm not a vet an in my experiance with erpitle start acting sick you need to go to the vet right away or things get worse.
