Yesterday, this duckling hatched with a little string connecting to what I think is a yolk sac. He's been trying to take it out but he is struggling. What do I do!
Hi there and
It looks like the ducks umbilical cord.
If you put the duckling under the brooder or heat lamp
The heat should dry it up and make it fall off.
Don't cut it as you may make the duckling bleed to death.
Goodluck,
Fionn.
