Sorry, I disagree. It may be simple raising chickens, compared to some other animals, but I have a healthy respect for the ability of animals to surprise me. The fact that either a chicken or a horse or a person can even exist, let alone have a personality and a curiosity is a miracle to me, and the more I learn about them, the more I enjoy them. The main reason even a child can learn to care for a chicken or train a horse is that children are brilliant, and they learn quickly when they are motivated by a genuine interest. They're pretty remarkable creatures themselves.
On the other hand, I've seen poor outcomes from people who purchase a pet animal and bring it home expecting it to be easy, and getting blind sided by the fact that they aren't machines, and they have needs and instincts. We have a dog that was adopted out by the local pound three times, and returned three times, because of owner issues, not dog issues. We have him now, and he's a wonderful dog. But people often assume things are too easy, and don't bother to prepare for reality.
Not saying you have to have a degree in veterinary medicine to raise chickens. But I have really enjoyed the learning curve, and I expect to continue to enjoy it once the birds have arrived.
