  Although the factory has selected the high quality breeding hens, there is a check before those breeding hens killed. Three days before those breeding hens killed, the veterinarians would sample survey those breeding hens' health. Once those veterinarians find any sickness breeding hens in the survey, the factory would refuses to take all of those breeding hens.
  The breeding hens which are safe after the check would be accepted by the factory. 

  As I learned, those breeding hens would have a growth period which take 42 days long, healthy forages are needed to be important. The factory makes three different kinds of forages for different kinds of chicken, one kind of forage for the breeding hens which are under 20 days, one kind of forage for the breeding hens which are under 35 days, the last forage for the breeding hens which are over 35 days.

  Different forages could ensure that the breeding hens in different time period get enough nutrition, in other words those particular forages could ensure the quality of the chicken.
