I have all of my pregnant females in the same nursery cage. Dont know the exacty dimensions but its a large cage meant for guinea pigs or rabbits. Yesterday my albino had 4 babies, then today I found like 6 more in her nest, and 1 in the food bowl, 3 in another nest and I saw my fawn pop out another. I was worried she might forget about the scattered ones so I placed them all in her nest. a few second afterward the albino the hairless and the mother came over to investigate me and wound up stepping all over that set of babies. I know first time mothers arent known to be the best, but I notices everyone left the other nest alone so I put it on the other side of the cage away from the food and water adjacent to the other nest. like ten minutes later I looked and there was one huge pile of babies between the two nests and the albino was sorting the babies into to groups. 1 baby had died but it didnt look like she killed her. This is my first time breeding rats, and im really not sure if I should let things run their course, or if I should move nests remove rats, give them a different substrate. (Im using newspaper and I feeld like they might be stashing a baby and unable to find it again) or what. if anyone could tell me what I should do if anything at all please let me know. I am just breeding them for my snakes, but if theyre going to be food someday they have to get that big first @_@ thanks in advance guys.
