What type of chicken do you have when it has dark reddish feathers and long yellow legs?

There isn't a single type of chicken with dark reddish feathers and long yellow legs. There are many breeds that share these characteristics, so it's impossible to identify the specific breed without more information.

Here are some common breeds that could fit the description:

* Rhode Island Red: A popular breed known for its reddish-brown feathers and yellow legs.

* New Hampshire Red: Similar to Rhode Island Red but with a more vibrant red color.

* Wyandotte: A variety of colors, including red, but often with a darker red shade.

* Australorp: Black feathers, but often with a reddish sheen, and yellow legs.

* Buff Orpington: Creamy-buff feathers, but sometimes have a reddish tinge, and yellow legs.

To identify the specific breed, you would need more details, such as:

* Size and shape: Is the chicken large or small, tall or short?

* Comb and wattles: What shape are the comb and wattles on the chicken's head?

* Feather pattern: Are the feathers solid red, or do they have other markings?

With more information, you can narrow down the possibilities and potentially identify the exact breed.
