Are Silkies good with other breeds of chickens?
So much of compatibility is dependent on the individual birds so there is no way to predict whether or not it will go well for your silkies. Some folks have great luck having them in a mixed flock and in other situations it turns out disasterously. What I would suggest is that you go into it with a solid "plan b" ready to go so that if you do see things starting to sour you are ready and able to address the situation - whether that means constructing a second/separate housing unit for the silkies or another option that would provide all the birds a safe, happy life. If you do want to house them together initially to see how it goes be sure that you design things to be "silkie friendly" with regards to their abilities to navigate up onto roosts, etc that can differ from other breeds -- possible points of issue in mixing them reach beyond just being behaviorally compatible.
