Special adaptationsBantam Chicken and rooster

  • Chickens have a comb and waddle, red skin flaps on the top of their head and under their beak, which help dissipate heat
  • Roosters will have a larger comb and waddle which are a form of ornamentation.  Roosters with larger combs and waddles tend to appear more attractive to hens
  • Some bantam chicken breeds are considered a "fancy chicken" and will have ornamental feathers surrounding their feet


  • Domestic chickens are too large to fly, but can glide and perch on tall objects
  • Chickens love the occasional worm or bug and will scratch at the ground in hopes of uncovering a tasty treat
  • Today bantam chickens are mostly used for show or kept as a hobby
  • True bantams are breeds that do not have a full size counterpart
  • There are several color variations (breeds) of Bantam Chickens.  At the zoo we have a bantam Leghorn, bantam Porcelain Mille Fleure Barbu D'Uccle, and bantam Sebright
