The present study aimed to provide further insight on different pecking behavior of beak-trimmed and untrimmed turkey hens in proximity to the feeding pan. Investigations were carried out in 4 housing compartments with female fattening turkeys where video were recorded and evaluated with regard to 4 different types of (pecking-) behavior (feeding, pecking on the ground, pecking at conspecifics, being pecked) observed in 1 focal animal in proximity to each feeding pan. Concerning the median duration, there were only small differences between the animals with different beak conditions. Pecking behavior varied in how many animals exhibited 'pecking on the ground' with more turkeys with intact beaks showing this activity in proximity to the feeding pan with a slightly increased median duration (0:06 vs. 0:04 min). Further discrepancies were observed in the maximum duration of recorded behaviors, as there were animals with intact beaks that showed "pecking on the ground" (4:09 vs. 2:54 min), "pecking at conspecifics" (3:46 vs. 1:25 min), and were "being pecked" (0:52 vs. 0:35 min) for a longer period of time. Based on this result, however, it can be assumed that especially individual animals with an intact beak forage more intensively and perform some pecking behaviors, which include injurious pecking, with longer duration in proximity to the feeding pan.
