I have a Black Cochin Hen, she is about 4 months old. Maybe a week or two off. Around her face gets really dark red sometimes, and then it goes back to light. It seems to change every few minutes (Can someone answer why that happens?). The Rooster has already fertilized her, but I'm sure this doesn't mean it's getting closer. And it's all about the same for a Americauna chicken I have. But she is about 3 months old (which may be a little early). She tends to hang out with the Rooster A LOT, but I'm sure this doesn't mean anything. I'm just trying to be very informative.
