I agree with
Grain Gypsy regarding the mixed breed flock; it can easily be done.
It is recommended that any newbies to an existing flock be quarantined for at least a couple of weeks to ensure that they do not have any health issues which can be passed onto the existing flock.
If you do go down the quarantine path then I definitely recommend getting more than one Silkie so that she has company while in quarantine.
Also, after the quarantine period, they will be company for each other during the integration phase.
Watch them carefully as Silkies are normally not as big as the LF breeds and while they can defend themselves, they are at a disadvantage size wise. Your Jersey Giants may appear friendly and docile but might not react well to a stranger or strangers in their flock.
The divider idea is a good way to let the two flocks see and interact with each other without the risk of being injured.
Having said all of the above, I have added one chicken to an existing flock, in an emergency and was lucky that she had a plucky chickenality and managed to dodge and weave initial aggression at her being there while still having the determination to be accepted.
It was kind of like, “Hey, I’m here, I’m staying .. get over it!”
