I guess it's a common expression in Australia
See The Australian Slang Dictionary
Clucky : Feeling broody or maternal
why doesnt he go out and just BUY one like nicole kidman and her freak ex did.
I heard and used both "clucky" and "setty" in Idaho in the 1960s referring to hens that lay their given number of eggs, and then want to sit and brood them, regardless of whether there are still any eggs to sit on or not. They would not lay any more eggs. A couple of days in a small coop with a wire floor broke them of that instinct, and then they would start laying eggs again.
