Choosing good chicks is a key step to obtain a high brooding rate. To breed chickens with consistent growth and high production, the first chicks must be selected. So what are the methods for selecting chicks?
The chicks should be from healthy and infectious bursal (IBD) negative breeders. If it is necessary to use chicks from IBD-positive breeding flocks, they must be separated, and only chicks from positive breeding flocks or chicks from negative breeding flocks should be kept in one zone, and not mixed in the same zone.
Chicks should be hatched from 52g or larger eggs. In broiler production, chicks hatched with smaller eggs must be bred separately and not mixed with other chicks.
Only chicks of MG (chicken septic enzyme body) and MS (synovial bursa enzyme body) and salmonella-negative breeding flocks were used.
Eyes are round and bright, alert and healthy.
The abdomen is soft and the yolk is well absorbed; the umbilicus is well healed and there is no infection; the villi around the anus are not pasted into a paste; the skin of the feet is shiny and waxy, not dry and fragile.
The chicks are uniform in size and color, clean, dry, loose and long, and shiny.
The chicks do not have any obvious defects, such as crutches, torticollis, eye defects or cross-beaks.
Adopting the “all in and all out” feeding system. That is, only enter the same batch of young chicks in the same range, feed the same age, and all play on the same day. After playing, thoroughly clean, clean and disinfect to cut off the circulating infection of the pathogen.
