The Yokohama breed is a breed best used as a show bird due to their ornate appearance and their poor egg-laying abilities. This appearance will be hard to maintain however as their long feathers make care slightly more difficult than standard chickens, so they are very much high maintenance birds.
Yokohama are not the friendliest of birds and tend to be very aggressive toward humans and other chickens alike. They are, at least, very full of character and given the space can be quite entertaining.
The Yokohama is most recognized due to their long, flowing tails. Held at nearly a perfect horizontal angle, the Yokohama's tail is quite a sight to behold. Their combs are fairly small, almost walnut-shaped, and is set forward on the head. Their wattles are small as well, as are their dewlops. They have a red coloration on their shoulders, yet another recognizable aspect of their appearance.
The biggest issue to keep an eye at is the Yokohama's long tail feathers. Then can very easily become dirty or broken, so it's important that you have perches placed fairly high up to avoid feathers laying in the dirt for too long. This also means they function best with clean, dry litter covering under their perches. If you intend to raise a show cock, keep him separate from other Yokohama to avoid damaged or broken feathers.
