I bought a couple chicks and a lone duckling (don't advise anybody to do THAT unless they want a house duck like nettie's) and the big ducks all run away from the babies.
LOL! thats happened to me x3
when i brought my 2 ducklings home, they were about 3 weeks old, the duck i have Rain ran away from them!!!
then the little tricksters wouldn't stop following her.
Eventually they sneaked up behind her and my little girl pecked at her tail
OMG DID SHE JUMP!
she cant fly but omg she jumped like a foot or more!!!
