Adoption

Have you ever seen any adoption among animals in your life before?!?
Found this interesting scene at my hometown
The ducklings were adopted by a biddy
All the ducklings follow whenever the hen goes...
And yes the ducklings eat what the hen found for them!
Actually this happened due to my uncle tucked in the duck eggs while the hen was in incubation
Wonder what is the respond by the hen when the ducklings hatched out and what will be the different with the other ducks when the ducklings grow up later?!?
LoL
