Seeds, a chicken favorite are low in vitamin A. The vitamin promotes increases resistance to parasite infection aside from promoting digestion and appetite. An obvious sign that the chicken lacks vitamin A is when the plumage lacks the usual luster, is pale, and is rough. There is also the lack of color intensity in the cere and there is yellowish and scaly accumulation on the beak. It may not be much. It could be a little droplet of water running across a wire, a territory that they are foraging even when there are no signs of potential food morsels, just about anything. The chicken sometimes could be cranky enough and peck at another sometimes to the death. This is sometimes complicated as when other chickens see blood, they could help peck the hapless chicken until most feathers fall or seriously wounded. First though, a good chicken nest box must be planned to get the chicken lay eggs in manners that are most productive. The basics are the same. You build a box, put in some straw or wood shavings and when the time comes so too the eggs. But when there is low egg production chances are something must be done to improve the nest box. Regularly moving the coop enables you to choose a spot where they can feed on weed. In this manner, you can prevent them from damaging any crops that you want to protect by veering the coop away from the spots they're growing from. Regular cleaning is also recommended to prevent diseases. Chickens love to perch, so don't forget to install a place where they can roost. Introduction of new birds into the flock without first quarantining the new birds is one of the most common sources of infestation. When additional chickens are needed the best way is to quarantine first the new flock in a separate cage for two weeks and examining and treating them for possible infections before being introduced to the main chicken house. 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.
