Mix Ameraucana and Mille Fleurs?

[Sunnychix]

I have 2 sweet Ameraucana's that live together in their own coop because my other birds would not stop picking on them, these 2 girls are gentle and quiet. I would like to get 3 mille fleur chicks and combine them with the other 2 girls (at about 10 week-old) Has anybody done this? I do not want to build another coop and would like these girls to live together if it is possible.

A couple tricks you can do
Put them on the roost at night. I've done this many times and even with a new rooster and they got along.

Another trick is put chicken glasses on the ones that do the picking.

And with adding younger/not full grown chickens is to give them places to hide. It can be something as simple as a board with a couple legs screwed to it. Something like an A frame shape. A box of some sort with holes cut in it big enough for the little ones but not big enough for the big ones.

One big thing is enough space to get away and do their own thing.

Oh and one more thing I've done is increase the number of new chickens introduced.
If you have 6 old gals and introduce 2 new ones. everyone is going to pick on the 2 new ones including one of the new ones will pick on the other new one.
If the flock dynamics is more even the amount of picking will be spread over more birds. 6 old gals and say 4 new ones.

You've already had trouble integrating birds...not sure I would recommend doing it again, especially if you don't want to maybe build yet another coop.
Isn't mille fleur a color pattern...often on bantam birds?

Did you ever resolve this issue??

Knowing more about your coops, dimensions and pics, might help garner more viable suggestions.

Meanwhile, here's some tips about....
Integration Basics:

It's all about territory and resources(space/food/water).
Existing birds will almost always attack new ones to defend their resources.
Understanding chicken behaviors is essential to integrating new birds into your flock.

Confine new birds within sight but physically segregated from older/existing birds for several weeks, so they can see and get used to each other but not physically interact.

In adjacent runs, spread scratch grains along the dividing mesh, best if mesh is just big enough for birds to stick their head thru, so they get used to eating together.

The more space, the better. Birds will peck to establish dominance, the pecked bird needs space to get away. As long as there's no copious blood drawn and/or new bird is not trapped/pinned down and beaten unmercilessly, let them work it out. Every time you interfere or remove new birds, they'll have to start the pecking order thing all over again.

Multiple feed/water stations. Dominance issues are most often carried out over sustenance, more stations lessens the frequency of that issue.

Places for the new birds to hide 'out of line of sight'(but not a dead end trap) and/or up and away from any bully birds. Roosts, pallets or boards leaned up against walls or up on concrete blocks, old chairs tables, branches, logs, stumps out in the run can really help. Lots of diversion and places to 'hide' instead of bare wide open run.
