I am really worried that my silkie hen may be a Roo because my last three chickens were, even though they were supposed to come sexed from the hatchery Anyways, she is 4 months old and hasn't crowed or tried to crow, and is a very quiet, calm chicken, I also haven't seen any red in her face develop, but for some reason her feathers make me nervous. Do these feathers look normal for a silkie hen to have? Thoughts? Thanks!!!
