To avoid overheating day-old chicks and prevent possible damage, hatchery personnel have to develop a keen eye for the signs that chicks are indeed overheated. Three questions that have to be answered lie at the basis of delivering healthy chicks to the customer time after time. What are the signs that chicks are overheated? What procedures can be put in place to identify possible overheating? And what can be done to prevent this overheating? These key indicators can help a hatchery identify when chicks are overheating, and so help improve chick quality and overall broiler performance.
