'Factory farms' provide safe food at an affordable price. Chickens on a farm such as Landwk's are more disease free than those coming to us from 'natural' farmyards. Their diet and surroundings are carefully controlled to avoids conditions that lead to rotten meat being transmitted to the consumer.
As a whole, we no longer have any idea of what goes into what we have to do to put food on the table. We maintain an idylic view of actually working a farm that is far from reality. I suggest that you actually kill and clean a chicken yourself to understand what is involved. Start by wringing the chicken's neck and then go through the process of plucking and dressing the chicken. This link will provide an overview of what you need to do to have a chicken ready to eat.

You can look up the videos on youTube. You will come to realize that chickens raised and processed in this manner are significantly more likely to bring disease to your table than those coming from Landwk's farm. They will also cost significantly more.
If you can make it through to putting the chicken you raised, killed and cleaned on your table, then move on to the work of putting beef, pork and lamb there. It is hard work that involves getting not just your hands dirty.
Farming is technologically advanced, perhaps more than any other industry in the United State. One hundred years ago, more than 90% of the US population lived on the farm providing food for the remaining 10%. Today, less than one million people in the US live on farms. As farming technology and productivity improved, more people were able to move to the city. This movement enabled us to have such things as electricity, indoor plumbing, paved streets, modern medicine, airplanes, computers, etc. Without 'factory farms' making the people available to do other work, none of these things would have been possible.
We enjoy better, safer, fresher, less expensive food in a greater variety than ever before. Frankly, I do not wish to go back. I support modern farming
