Present-day strains of laying hens will usually be less productive in a short period of time if they are not properly managed. Commercial-hatching hens will not be removed from the flock after being placed in the stock, unless sick or paralyzed. Chickens that are housed in a small herd should be removed about 2 to 3 weeks after being placed in the ovary, making the birds have much time to adapt to the new environment around them and produce peak production. There is also plenty of time for the slow progression of the physical maturation of the limbs.
Often, one can distinguish one another by observing the status of the crown and the characteristics of the head, non-laying hens or low-yielding birds. Also, if the bird is capable of laying a good chicken, it can be done through the characteristics of the body. It is usually recommended that birds be removed at night because they are less likely to be anxious and less susceptible to egg production. The flashlight combined with a blue cellophane lens enables the selection of low-production birds without anxiety. On the other hand, the movement of the birds should be large enough to not cause much damage, if the majority of the flock suffers from disease, recovers from trivial disease, or if the butterfly is gone. The bird has to be delayed because the removal of the herd or the goose herd often causes a number of laying hens to b The headers should also be removed.
