Two Hens Mutually Brooding: a rare behaviour in <i>Gallus domesticus</i>
Abstract
Two black broody hens of breed Gallus domesticus both laid their eggs and brooded in the same nest, with no conflicts. The nest was in a high place away from water, both brooded and shared the same brooding cycle, (brooding, dust-bathing, eating, drinking and brooding). In spite of their cooperation, they both still manifested clinical signs of anorexia, weight loss, wasting of pectorialis muscle, and loss of feather luster.
