Orphan pups are less likely to do well when placed with a surrogate. This is often due to the fact that if she is nursing her own brood, the older pups will push the younger pinks away from the mothers teats, and while they can survive, they will not thrive as well as the older pups.

My advice is to not breed the hairless again if she proves to not lactate very well.

In the meantime, check her pinks late tonight and check for full milk bands in their belly. If they don't have milk bands, she is likely not nursing them. If it's the same in the morning, they will need to be given to another mother with pups near exactly the same age.
