Weighing almost 2lb and measuring 12in in circumference, this is very far from your average egg.
And while 12 free range hens' eggs may cost you £2, a dozen of these would set you back £72.
For this comes from the rhea, a flightless South American bird whose eggs are growing in popularity as a delicacy in Scotland.
At Corrie Mains Farm in Mauchline, Ayrshire, four rheas are attracting attention from visitors intrigued by the sight of a creature usually more suited to foreign climes.
Anne Smillie, who runs the farm, said: "The rheas are South American ostriches.
"They love it in Scotland. They are very hardy birds and, although they have a shed to sleep in, they choose to sleep out at night.
"Their eggs are fairly rare, which is why they are that bit more in price.
"They only lay in the summer when there is a run of six or seven really warm days.
"A hen might lay six eggs a week but the rhea need a warm spell before they decide to start laying.
