Some time between March and May, when she is 26 to 28 weeks old, an average hen will lay about 100 eggs. The female usually lays 4 – 5 white to buff-colored eggs in a well-hidden nest and then incubates them. Guineafowl (/ ˈ ɡ ɪ n i f aʊ l /; sometimes called "pet speckled hens" or "original fowl") are birds of the family Numididae in the order Galliformes. They are endemic to Africa and rank among the oldest of the gallinaceous birds. A domestic guinea hen lays seasonally, just as her wild cousins do. After hatching, both parents participate in rearing the keets together. They also have a very thick shell and require a crack with a knife to break them. The eggs are deeply flavoured, with large golden yolks and surprisingly tough shells. Domestic Guinea fowl eggs are smaller than hens eggs, by about a third, but have much the same taste and a surprisingly large yolk. They are smaller than standard chicken eggs – more like bantam size – but their richness makes up for this. Guinea fowl will lay anywhere and everywhere, particularly favouring large clumps of nettles.

Most Guinea fowl will lay about 120/140 eggs a year … The Crested Guineafowl is monogamous with strong and long-lasting pair bonds.
