There is not much study to support this but the fact is man will only be preyed upon when a predator is starving and there is nothing else available, when a predator is sick and is unable to hunt or is very old that their movement and ability has been limited, when the animal is threatened with its back to the wall and escape routes are closed and sometimes when a man is mistaken for another identity. The Design - Typically, a chicken will need about four square feet of space and three hens could share a nest. Each hen will also need a perch about 9" long. The design should also include a hatchway, storage area, ventilation, lighting and a feeder system. For a cleaner and healthier environment, design the floor to accommodate deep litter. When they do, they will throw amicability to the nearest window and peck at their companions and if the hapless companion does not pay attention fast they could peck at that one even to death. On the other hand if there are the so-called birds of prey, chicken are the most ideal birds to prey on. Keeping them safe Raising chicken will require among other things a sunny dirt run for them to roam about and scratch around. Commercial hens usually get replaced after two years, but some owners, especially those who keep their hens as pets, collect eggs even from those that have already reached the last stages of their lives. This won't pose a problem since hens are still very capable of laying eggs even in their later years, albeit a lot slower, until it eventually stops. The Waste Products Of Your Chickens Can Be Utilized As Fertilizers. It has always been noted in many sources that chicken waste is one of the best fertilizers around for its high amount of nutrients and nitrogen, which can help your garden produce vegetables at a faster rate. And the fact that they're organic makes your crops free from harmful chemicals. It will also be practical as frequent intrusions disturbs chicken and that destroys eggs in the process let alone the muck that you will help splatter around. In place of the egg chute, construct the chicken nest box with doors constructed at the backside so that you could collect the eggs from outside the coop without disturbing the chickens very much.
