Okay! Do you have your silkie with other hens and roosters that are hard feathered?
My silkies are part of a mixed flock of various breeds. They are all happy and thriving.
You will get your submissive and dominant chickens in this breed just as in any other, though they aren't known as particular bullies.
As someone else said, ensure their crests are trimmed if needed. Mine don't have massive pouffes so I don't need to.
