So we've had this duck egg in the 'bator for just over four weeks. Ana candled it today and pronounced it dead. She asked if she could open it up and take a look - she's always curious about how far a chick/duckling developed before it died. She cracked the egg and dumped out a duckling with yolk still attached. Ana picked it up to take a closer look and the duckling was breathing! I had her put it back in as much of the shell as she could and then put it back in the incubator. I know we probably killed the poor little thing but is there anything we can do to help it at this point?
