silkies are very hard to sex before 4-5 mos. old. You might post pictures on the "Silkie thread," You would need good, clear, closeups - it's impossible to see the comb in your picture and you also need a good profile photo
Btw those are not my fingers, those are my moms! She had to come help hold my little rat and do that so I could get a picture! Delilah is a fighter! She does not want star quality!
Glad to have you join us! I don't know much about Silkies, so I can't help you with the gender. Try posting in the "What breed or Gender is this?" threads, or try asking people on the Silkie threads who know more about the breed.
