If it was first litter it could just be the doe not realizing what to do or slow birth. More likely though you check
alot and she kept halting everything when people would come by again. Its not good for her or the kits and i highly recommend just leaving her totally alone the due day.
Feed her late the night before and the next day do anything and everything to forget about her for the day.
You wouldnt wanna be poppin out babies with a horde of onlookers would ya?
I have had the same thing happen when i first started. That could be the reason some were dead.. could be.. they were right there ready to be born and then momma halts everything and they are stuck squished in the canal until she decides its safe again.
But its possible they just were stillborn before due time. It happens.
