No. In fact it is not. Chicken may be very low maintenance birds but they have survived longer than us and their population is several hundred folds over ours. True they are prone to diseases and pests but their population is a testament that chickens are survivors. More so with hands that care.
Chicken will eat just about anything. They will scratch for worms, they are happy with people leftovers, they love pellets, seeds and vegetables, peels, bugs and slugs. They are just as happy eating bread while pecking at a cockroach, and when something is not right with them, they will eat grass and even pebbles. They are most content when they range around for food and they will know what to eat and what not to every time. On the other hand, people could prepare the fanciest feed preparation for them but if they do not want it, they will avoid it.
