I assume they are dwarf pups?
Did you separate them before the birth of the pups? She may be stressed after the escape and also may be due another litter as they do mate immediately after birthing.
At 3 weeks dwarf pups will do fine in single sex groups. 11 is a lot in one cage. I'd separate the males in to one group and keep them together and give them plenty extra foods and supplements. Maybe leave her with a few of her daughters or if she does have more pups then remove them all to a female only group. They need separated at 4 weeks anyway so mum can recover. She may be getting tetchy with them now with so many as they jostle to suckle even though they don't need it at this age.
