Setting a those pesky trolls aside
..there are so many good books and other information on-line as to what chickens are and are not. I personally suspect that people cannot or will not read about what to expect out of their animals.
I have had a lifetime of raising birds and animals. I am no nearer being an expert than before. Before I ever did anything, or obtained any animal, I did my homework. I was then armed with the wisdom of others so as to not let my creatures suffer from my ignorance. Of course that never stopped the unexpected from happening. However, then and as now, I am better armed in handling situations.
Since childhood, I have always sought the best information on the subject that interested me. How to raise and care for living things is not so much a mystery as an art. That is probably why I decided not to have children. I knew my limitations.
There are chickens and there are chickens. Some lay right away and some take their time. Some accept confinement better that others, and some convert feed more efficiently.
However, to everything there is a season. I personally am allowing natural light for my birds. I did choose to have birds that lay throughout the cold weather
which is usually the dark winter months on this planet.
I have no patience or charity for those who rush blindly into obtaining animals or any other living thing and expect the animals to run like a well-oiled machines. It aint gonna happen.
