I see you are in Texas. That means you are north of the equator so the days are as short as they are going to get. The length of day can have an effect on them starting to lay, especially decorative breeds. BA's are a production breed. Some will still delay laying because of the length of day but they can be much less affected by that.
I've had BA's. These were raised in the spring and came into lay in summer. If I had 10 BA's (or other production breeds) I'd expect to get the first egg or two somewhere around 18 or 19 weeks of age. By 24 weeks, your hen's age, I'd expect half of them to be laying, maybe one or two more than half. I'd expect the last of the 10 to be laying by 27 weeks. I've had a few go longer but, in general, if they are not laying by 27 weeks they have volunteered to be eaten. As a pet she is safe from that with you.
I've had some pullets start laying in December, with the shortest days of the year. It does happen but I've also had some wait.
I don't know how many you have. You have to have enough for averages to mean something but to me it sounds like you have been extremely lucky to get so many laying this early even ignoring the time of the year.
Her face looks kind of red but her comb doesn't. Maybe it is a trick of the light. A dark red comb is a sign that they might be getting close to laying. I'm getting mixed signals from her. She may be close, it may still be a while.

Good luck. I would not be worried about her health at all. She looks great.
