Four-legged hen skeleton

This specimen has a particular scientific value since it has been the subject of a publication of Emilio Ninni in 1899, titled "On the skeleton of a monstrous bird". Here, the Venetian naturalist describes in great detail this hen, bought alive at the market in Treviso, reporting its behavior and analyzing in depth its skeletal deformity. The publication is enriched with an illustration of the abnormal bones with the relative measurements and description.
