Noticeable fluff production starts three to six hours after the first chick has hatched from the shell. During that time, the typical ventilation volume is approximately 5m3per hour for each 1,000 eggs/chicks.
A New Approach to Evaluate the Hygienic Condition of Commercial Hatcheries
Hatchery hygiene was evaluated in two commercial broiler hatcheries using open-plate method, surface swabbing and microbiological examination of hatchery fluff. Air samples and surface swabs were collected from: inside the hatch unit, the corridor outside the hatch unit and the chick processing room, while, fluff samples were collected after ...

Microbiological Monitoring of Hatchery Sanitation - ScienceDirect
1983年2月1日 · Wright and Epps (1958) found that the microflora of the fluff, produced by hatching chicks, was a reliable criterion of the sanitation condition of a hatchery. Sanitation ratings of A, B, C, or D were given to the hatcheries monitored based upon a standardized bacteriological technique outlined by Wright etal.
Fluff production in HatchTech hatchers The HatchTech R&D Department measured the amount of fluff expelled from both the 28800 and 42240 hatchers.
