I hate to bring bad news to the happy ending, but the black one was the one who harmed them it seems. After leaving them alone for 5 minutes to see what they would do, the black one was pecking at it’s eye. (Thinking the black one could be trying to get rid of the other males, as he left the other one alone for the most part.) so I removed the black one and everyone seems so much calmer.. so I don’t know what to do with the black one, for now I got him in a tote with a mirror for now. Not getting him any siblings incase he kills them too. The “clinging” was to hide from him, by getting under him.
