I had one mom drop 10 pinks last week and 2 more moms drop 15 and 12 pinks respectively and they were all in the same tub and I noticed that only 2 of the moms were nursing/taking care of them so I took the bad mom out to go back with the male and left the two good moms to take care of the 37 babies togeather and they're doing an outstanding job! What's kinda cool about it is that they will take care of them in shifts, one mom will take care of all of the babies at once while the other rests and then they'll switch...its pretty cool.
