Breeding back to back and weaning age?

I crossed over to the Herp community from the rat community, so I'm used to the 'no seperating before 4 weeks' mentality. I know there are breeders who breed back to back, however, so I have to ask. Is the three week minimum safe? From misadventures in fostering, I know that mothers won't nurse babies of with significant age differences, so would it be safe to seperate them at 3 weeks if they've just dropped another litter?

I separate at 3 weeks if there's another litter. Haven't had any issues as of yet. If you're worried, you can do 3.5 weeks. My babies have been pretty big, eating very much on their own at that age.

I wean mine at 3 weeks unless it is a large litter.

In your case you will have to otherwise the new babies will not stand a good chance, the mother will nurse them all but it will be difficult for the new babies to get nursed because of the older ones.
