Archen doesn’t eat the kibble sold in most stores. It must be fed special berries grown from ferns that existed during its time, or sausage curry. Ecologists don’t think it can be reintroduced to the wild, but it’s popular enough with Trainers to not be a problem.

Archeops only clumsily flies for short periods. It could probably fly better if it tried harder, but it never makes the attempt. Archeops gives up on problems immediately if it faces obstacles, making it hard to train. That said, it learns quickly, so it isn’t impossible.
