It's a close call, but the longer, racier shapes and the low angles of the tails still have me thinking they are Phoenix bantams rather than Dutch bantams. Dutch bantams have tails carried at a higher angle. That's my take, anyway.
The colors are black breasted red for the female and golden for...
Why not get a mix of different types of Easter eggers? Whiting True Blues, Whiting True Greens, olive eggers, a few of each.
Whiting True Blues and also Prairie Bluebell eggers are mixed with Leghorns already. They are the same thing under different brand names from different hatcheries, and...
Sussex have white legs/feet. This might be a Sussex cross, but it is not purebred as Sussex do not have beards like this hen has. If it is from a store/hatchery then I agree it is an Easter egger of some sort.

Sounds like a war zone! Some people are beyond crazy and it is not fun to have to deal with them. I hope happier and safer days are ahead for you and your flock.

2. A chicken/chickens from somewhere are stopping by to lay eggs in your nest box.

If they only recently started laying, that...
I agree with using food. What I would do is to take out the feeder when you put them to bed. In the morning, put some feed in it and play a game of follow the leader with the feeder. If they are hungry enough, they should go for it. Do this a few times, and they should get the idea. Maybe...
Integration is always dicey, but hopefully everyone will get along after they settle in. As long as they have enough space and there are places where the less dominant birds can hide then she should be okay. Most chickens are much happier outside.
