Next time give them a separate litter box a few days before they get their nest box. And if you see that they are hanging out in the boxes too much remove the boxes and only allow them to have them twice a day for 10 minutes. That's all the more the kits will need to nurse. A smaller nest box may help too. Sometimes its just the first time they have issues.
I would rebreed in 2, 3 days.
