I have always raised mine in the barn, they will need to be separated for a bit, you can slowly start putting them in with the others with supervision, but put them back in a separate pen at night until you feel they can handle themselves.
I have gone through similar situations as you did when I used to breed, they always picked the coldest days to kid and I had to pull some for a few days but then they went back out to the barn, some moms took them, others didn't. Currently I don't breed as I couldn't handle the baby drama, though I miss watching them hop.
