In the candid video, the adorable chick snuggles up to Rob, who laughs before saying: “You're a good chicken.”
The sweet moment seemingly delighted Rob’s fans, with one taking to Instagram to write: “Oh wow. Never seen such an affectionate chicken. Sweet.”
Another person added: “Marshmallow seriously the best name for a chicken Soo cute!”
A third person added: “Awww best friends! Marshmallow is the sweetest!!!”
Rob’s family menagerie announcement comes after he recently posted a shocking snap of himself with two pythons that proves he's definitely walking in his late father's footsteps.
“Found these two grumpy little guys on my afternoon bike ride around @australiazoo,” Robert captioned the photo, which showed him with the two serpents around his neck.
“Carpet Pythons along with many other native species roam wild at Australia Zoo but they were a little too close to our bird aviaries!
“We’ll be relocating them to a safer place where they won’t eat our birds or accidentally end up in a crocodile enclosure!” he added.
Robert also shared a shocking short slow-motion clip of one of the snakes lunging forward towards the camera, as it was being filmed.
