rejection

[Mel23]

Hi, i am new to the forum I am hoping that someone can help, I have 3 goldlines and 3 bluebelles, they have been living together for a year quite happily, but yesterday they suddenly decided to furiously attack one of the bluebelles, we took her out and she spent the night away from them, we have opened their enclosure and they are roaming the garden together, but they are definately a 5 and a 1, the 1 bluebelle seems very nervous with them and they are pecking her as she gets close to them, please any advice would be welcome! thanks

Maybe they are just reestablishing the pecking order .. So one wants to move up so they duke it out .../.

Is there one bird you can identify as the aggressor, the one that starts all the mischief?
If so, that's the bird I would remove for several days, perhaps a week. Keep her isolated from the flock, with no way to interact with them. It will knock her down in the pecking order and by the time she returns the tables will have been turned, with her at the bottom.
It's a proven way to teach a chicken some manners.
