Calypso or Cal? We only have one silkie in our flock so I have nothing to compare except looking at photos online. Ours acts very henlike - pecking around all day, steals food from others and runs, and never stands alert with the roosters. The tail is low and level with its body, not upright. This is a hatchery stock bird so I know it'll be easy for anyone more familiar with silkies (But not me!) My suspicion roots from those new feathers on its head. Now all our chickens in this age group are filling in with their adult feathers, so are those really "streamers"...male?
