If there were anything to evolution, chickens would regain the ability to fly as well as ducks fly. There isn't, and they don't
You are either joking, or seriously do not understand even the basic concepts of evolution.
By your logic, the ostrich should be able to fly, because flying is somehow better than not-flying. This is your own clouded viewpoint of what constitutes "better".
To you, it may seem that it would be better for a reptile to have legs than not, but in some environments legless reptiles fare better than those with legs.
Also, you should take care to use domestic (artificially selected) animals as examples to disprove evolution.
For example, it's like saying we should expect to see dachsunds become wolf-like over our lifetimes, and that because we do not, evolution must be incorrect.
Now imagine we dropped a large herd of dachsunds in the wilds of Alaska, they managed to survive, and we came back in 10,000 generations: if the descendants remained absolutely unchanged from the members of the founding population, that would be some evidence to counter evolutionary thought (unless dachsunds are somehow already perfectly adapted to life in Alaska, which I doubt).
It is more likely that
if the population managed to survive, they would have noticeable adaptations, such as much thicker coats.
