Welcome to BYC! Glad you decided to join our flock. You've received some good advice from the other members regarding your Silkies. I used to have some Black Silkies, and they did fine with calm and gentle, standard breeds like Australorps, Orpingtons, Brahmas, and Cochins, but with more aggressive birds they will definitely get badly bullied. Golden Sex Links are one of many labels under which Red Sex Links are marketed, and Red Sex Links can occasionally be aggressive, so I would not personally put the Silkies in the same coop with them. Good luck with your flock.
Yes, they do seem to have a bit of an aggressive side.
