Oh the good old chicken, the most common domesticated animal in the world. There are more chickens in the world than any other bird, as one might imagine given that most people eat their eggs and meat.
Sorry chickens, but it's true! Not to mention the countless chicken jokes (how many ways and times can the chicken cross the road?). And who can resist a good old rubber chicken?
Chickens come in all different colors and color patterns. There are your browns and blacks and your spotted chickens, your multi-color chickens with browns and blacks and reds and whites. Roosters, or male chickens, have a red comb on the top of their heads. They also tend to have more striking feather colorations than hens, or females.
Chickens live in a flock together, with a determined pecking order amongst themselves. Chickens higher on the pecking order are first to access food and and establish the best nesting locations. Chickens lower on the pecking order are literally pecked at if it steps out of turn. They need to wait for the other birds to eat, for example, before it is allowed to take its turn. Chickens generally eat seed, especially in captivity. They also eat insects as well as mice.
