Should I leave her?

Betty my 14 week old speckeldy was being pecked, quite badly by 1 of my ex batt's, All part of the pecking order i know. Anyway I seperated Betty yesterday, Put purple spray on her etc. Tonight, i have just been out in their run playing with them until bedtime, I tried to put Betty back in the rabbit hutch i bought for her yesterday but she was having none of it, Kicked up a right fuss so i put her down to open the other door and put her in there, But she took herself off into the main coop with the others.

I've just been back out and all is quiet, But should i leave Betty there? Im worried the ex batt might attack her again in the morning before I get out there to them.

Thanks  Just wanted to make sure i was doing the right thing, Will set my alarm a little earlier in the morning so im up and about just incase
