The three ducklings that finally hatched last night still have one very tiny peice connecting their "umbilical cord" to the egg...I planned on leaving them in there to dry out but it is starting the smell really terribly and I'm concerned about bacteria. Should I go ahead and finish detaching them? Although they aren't up and running yet (who could expect them to be after such a terribly eventful hatch) they are very vocal and kicking around so I'm not concerned about them too too much (although if you think I should be please let me know)...the bulges on their belly buttons are going down slowly but consistently.
