Removing unhatched eggs

This is now day 25 for my broody bantam, Bianca.  She has so far hatched out one chick (on Easter Monday) which is healthy and lively.

I really feel I should be thinking about removing the unhatched eggs now.  My idea is to remove them when I open the pophole tomorrow.

What do people think?

She still seems to be sitting tight.  She goes out once or twice a day and the other eggs are still warm to the touch.
