You should be expecting more clutches every 25-35 days of 2 eggs. If you leave the female with the male you're going to keep getting eggs.
If you seperate her, she will lay until she is done since female cresteds retain sperm.
I'm doing my first breeding right now and I'd suggest putting a small little bowl of pure calcium dust in the for the female. Giving her crickets once or twice a week that are dusted will help. You want to make sure she doesn't get low on calcium.
Also you should put a "laying box" in with your girl so she has a place to go.
Sounds like your doing good so far
