I just got 3 new babies about 3-4 weeks old. Their eyes look like they could open any day. Anyway, the tree cutters brought them to me with their nest. One has a nasty looking scratch across his arm, but no break. I have never really had the actual real life, momma-made nest for babies before and i kinda hate to uproot them. However, they have fleas and I am going to pick up some diatomaceous earth tomorrow. My question is should I keep the nest for them to stay in (after I treat it of course) or should I get them cleaned up and in a proper human-momma made home? Any thoughts?
