I purchased these straight run Silkie Bantams at TSC on 3/22. They were on sale for $1.99 because they were more than a week old. That makes them about three months (90 days) old or close to it. I haven't heard any crowing yet, but I think one is a male and one is a female. Can you help me determine gender? Suspect #1 (I think is a hen). It has short feathers on the top of her head, a small comb, and small waddles. Suspect #2 (I think is a roo). It has a long feathers on its head, a larger comb, and larger waddles. Am I right to think I have a hen and a roo?
