The likely hood of them all getting along is quite high. Truthfully, if you start having problems, it is not the breeds but much more likely to be the space. What starts out as enough space for chicks, shrinks as the chickens grow.
 
IF you start having problems, reduce the size of your flock by a couple head, then wait a couple weeks and see how it goes, if it is still stressful, then reduce again. Through trial and error, you will find a good number for your set up. It is not black and white, but the BIGGEST problem in chicken society is not breeds, it is space. Make sure your run has hideouts, different levels, pallets on blocks, can allow some chickens to get up off the floor of the run, Lean up a pallet against the side, gives some shade, and some out of sight time.  While adding things to your run, may make it look more crowded, it actual gives your birds more space, and space that they can get away from each other if they choose.
 
Space is the biggest issue, not breeds.
