Well, like horses and many other animals, chicken genetics have two main parts: red "ground colour" and black for markings. There's also "lavender" and some other rare recessive goodies. Similar interactions happen as with horse genetics; we get all sorts of colour dilutions like smoky, blue, cream, dun and so on. :D
Some other horselike colours are just visual coincidences, but still neat. Such as this "zebra" (black and white Barred feathers). Or "flaxen chestnut". Or another "appaloosa" lookalike (Spangled - the tip of every feather is coloured, while in Splash, a few random feathers are all coloured from the start).
... aaanyway, back on topic. With my super duper new squad, I managed to fight my way straight to the Portal with no losses, and trade for the second time. Then got kicked off island due to lack of space, hehe, but nevermind.
The battlefield is a lot more fun when you're able to compete properly. :) Now I am really hoping BeastEon will have some kind of difficult, competitive challenge like it...
