Title: Analysis of the nesting behaviour from laying hens in a floor system.
Abstract: Summary Analysis of the nesting behaviour from laying hens in a floor system Two flocks of the Lohmann Silver strain (N (LS1) = 366,N (LS2) = 353) were tested for their individual nestingbehaviour at the experimental station Thalhausen, whichbelongs to the Technical University of Munich. For 12 orrather five 28-day laying periods the laying hens, whichwere tagged with a transponder, were reliably identified inthe Weihenstephan Funnel Nest Box. Automatically regis-tered was the time when each hen entered and left the nestbox, as well as the exact oviposition time.The hens started laying briefly after the beginning ofartificial daylight and they had laid up to 90% of all eggs inthe following five hours. The du ration of stay in a nest boxwith oviposition, took an average of 30 minutes anddiffered greatly to that as eggs were not laid, which took anaverage of 10 minutes. Further variations of the duration ofstay in the nest box were observed according to the ratio:nest box to hen. When the ratios were high, or during themain laying time, when most of the nests were occupied,the hens were stressed and they left the nest box earlier
