Anti-crow­ing col­lar?

Your Chickens - - Ask Our Experts -

QSome­one was talk­ing about an anti-crow­ing col­lar and then it was men­tioned in the Novem­ber Your Chick­ens. How does this work? It said that the bird’s vo­cal chords were re­stricted – is this OK wel­fare?

AVic­to­ria says: I did laugh when I read this in YC. The anatomy of the hen was ob­vi­ously not known by the ‘in­ven­tor’ of this de­vice. Un­like mam­mals, the voice­box of a chicken is not in its throat but at the base of the tra­chea just be­fore it di­vides in to the two main bronchi (lung tubes). This voice­box is called the sy­rinx and it is more com­pli­cated in its fea­tures due to the fact that some birds sing, oth­ers can mimic speech or make var­i­ous dif­fer­ent sounds. I re­alise that a crow­ing cock­erel can­not be ac­cused of singing, but the tra­chea is open in the throat (have a look in the mouth of a hen some­time just by open­ing the beak) and there is no lar­ynx here at all; all of the sounds come from the sy­rinx in the chest – thus, the anti-crow­ing col­lar won’t work.
