Read MoreThe performance of nest building by domestic hens: is it more important than the construction of a nest?
Nest-building behaviour was not [emphasis added] inhibited by the existence of a preformed nest. This finding does not support the hypothesis that animal welfare in intensive housing can be safeguarded merely by providing that environment which would have been created...

Caging laying hens restricts movement, reduces bone strength, and affects foot conditions and plumage quality. This experiments determined whether providing perches influenced these variables. There were five treatments: front perch, rear perch, front + rear perch, long perch and control...
