I've recently become the owner of 4 proud mice parents, and have some questions regarding the ways in which mice care for their young. Perhaps this isn't the best forum to discuss this (maybe a more rodent-centered forum would be better), but I figured I'd give it a shot anyway.

About an hour ago, I moved two of my mice and their pinkies to a new, cleaned enclosure (as per the countless advice I've received from various sites) on their 3rd day of life. I've noticed now, that the pinkies are being slightly scattered around and away from the group that they were usually in. The majority of the pinkines remain in their group, but 2 or 3 of them have either moved, or have been moved by their parents a few inches away individually. I'm wondering if this is directly related to them having been interacted with by myself, or if this is normal after a few days from being born. It almost seems as if these few mice are being singled-out as if they're going to be shunned by the parents. So far, not hostile action has been witnessed. The mother and father are constantly roaming around the cage kicking substrate around as if to be buidling a new nest, but there doesn't seem to be any rhyme or reason to it, and the father actually did it once in the pile of babies, kicking one of them a few inches away - do you think he did this on purpose, or accident?

If anybody knows of a nice rodent-based forum that I should take this question to, I'd appreciate a link Thanks in advance.
