I agree. As she is a 6 month old and it is her first time, I'd put a few less than the maximum under her for her to hatch. But as soon as the hatch is over, I'd give her a few extra chicks to raise, slipping them under her the first night the incubator chicks are dry. I just think she'll do a better job than a person.
I'm sure you know this, but don't let the eggs cool off too much when you are taking them from the incubator to the hen. If you candle, you might candle them, mark the ones you select and put them back in the incubator to stay warm. Then, when you are ready for the switch, take them straight from the incubator to the broody.
You don't absolutely have to candle, but it is a good idea. I'll put a link here, but you can get good info by doing a search for candling. This link is to the learning center with this site.
I've never candled as I have yet to hatch chickens in this modern age. I will next year if I get a broody hen. For you, the eggs will have just started developing and it could be difficult to tell which are developing. If you do candle, don't toss any you are not sure of and try to select the best to put under the broody. The best means not only the ones you are pretty sure are developing but the ones that so not show any shell weaknesses, such as lines that could be cracks.
I'd want to get the eggs under the hen as soon as possible. She is much less likely to lose electricity, overheat, or cool down than an incubator. And do make the switch at night.
