So I have a duckling that’s momma broke the egg open before it was fully ready. I’ve had him in the incubator for 2 days and his umbilical cord isn’t drying out. It appears that the yolk has already been absorbed but his belly is still distended. I gave him a little nutridrench, and put neosporne on his cord to help it not get infected. What else can I do for this lil one?!?
