• Productivity and mortality of laying hens in aviaries: a systematic review (2005, background): “Kjaer and Sørensen (2002) experimentally investigated, among other factors, the effect of genotype on feather pecking and cannibalism of hens housed in small-scale free-range systems.”
• Selection method and early-life history affect behavioural development, feather pecking and cannibalism in laying hens: A review (2008, background): “Line differences in plumage condition and in feather pecking behaviour suggest a genetic background (Hughes and Duncan, 1972; Ambrosen and Petersen, 1997; Wahlstrom et al., 2001; Kjaer and Sørensen, 2002; Hocking et al., 2004; Uitdehaag et al., 2007).”
• A review of key health-related welfare issues in organic poultry production (2009, background): “A higher level of feather pecking has been correlated with higher mortality, although this relationship is not so clear for other forms of cannibalism (such as cloacal cannibalism or vent-pecking) (Hughes and Duncan, 1972; Allen and Perry, 1975; Kjaer and Sørensen, 2002).”
• Free-range Poultry Production - A Review (2005, background): “, 2001), indicating that a continuous selection for higher productivity results in birds having an increasing tendency to perform feather pecking unless precaution is taken to reduce it (Kjaer and Sorensen, 2002).”
• The risk factors affecting the development of gentle and severe feather pecking in loose housed laying hens (2010, unknown): “During an observation period every bout of GFP or SFP was recorded, where a bout was defined as a sequence of pecks not separated by any other behaviour or a gap of more than 5 s between pecks (e.g. Kjaer and Sorensen, 2002).”
• Farm level factors associated with feather pecking in organic laying hens (2003, result): “However, 2 .”
