You will really aquire many
friends here regardless of a person's sexual orientation. In my opinion feel free to post as long as you remember the BYC's rules and regulations .
Most silkies are like that very gentle and will have a best buddy. I have a satin naked neck silkie hen and a frizzle naked neck silkie hen that are inseparable. If I had any silkies close to the 5 month age I would have sent you pictures to help you see the difference between pullet and rooster.
Your silkie looks like a pullet . By no means am I an expert but my 5 month old silkies had combs like that. Should start laying eggs soon .The roosters combs were much bigger. I hope this helped you out .
