It is very difficult to integrate a single bird into a flock.
It is even more difficult to integrate a single bird that looks so much different than all the others into a flock.
How much space do they have?
How old are the ISAs?
How old is the Silkie?
How long was the Silkie in the 'look don't touch' confinement area?
Did ALL the ISAs attack her or just some? If during the 'look don't touch' confinement one ISA seemed to be nicer to her than the others you could try putting her in with the Silkie (as long as there is plenty of room in the confinement area and some place where the Silkie can hide away if she needs to) and see if they can bond. Then try integrating them both into the flock.
Failing that, I would look for a new home for the Silkie with someone that has other Silkies or make a new coop and run for her and get her a Silkie friend.
