thanks.She may be getting up because she feels as if the eggs are getting too hot. I've hatched under a broody in 20 F degree weather where the mom almost never got up. And I have also hatched a batch in the middle of summer, at 100 F degree temps where mom had to constantly get up to keep her eggs from getting too hot. As long as it doesn't seem like she's abandoning the eggs I think your girl will do fine.
day 2 with the real eggs and she got up to eat only. all the eggs covered nicely. I put an extra shade cloth and she should feel more comfortable in her cage.
