Yes I try to keep in contact with those that purchase eggs from me when I can. There's some that send me pics of their birds and first eggs, and others that only message if they have issues or questions like gender. Some I may not hear from ever again or until Spring if they want more eggs, but I keep their numbers saved.Talk to the person and ask how their fertility has been, folks like @wrathsfarm and myself keep track of these things (even with people who have purchased hatching eggs when possible) so we know what we're working with. 6 eggs should be a good start for a first time broody if fertility is high.
Your girl that's low on the pecking order? I've had to separate some especially if they're in a favorite box. Too much bullying leads to busted eggs.
I have Angels nest box that's sitting on Solos eggs blocked off with HC as she'll get bullied out of the nest. All the brooders were occupied or I would have moved her already. So once a day I let her out, and block off her eggs until she returns. She broke one egg herself within the first 2 days so I replaced it and all 11 are still intact so far.
