The aim of this work was to study changes of eggshell temperature (EST) during short-time egg cooling using thermography measurements in order to monitor a course of chick embryo development. Eggs (n = 600, broiler line ROSS 308) were incubated in Petersime setter S576 in temperature (T = 37.8 C) and relative humidity (RH = 51%). The EST was measured with the infrared camera Thermovision A20 (FLIR Company) from the first (E1) until the 19th (E19) days of embryogenesis. The series of three EST measurements was performed outside the incubator (T =22.4 C, RH 75%), i.e. immediately (EST-0), and then at 15 (EST-15) and 30 minutes (EST-30) following the eggs withdrawal from the setter.
