The consumer demand theory, relating to the elasticity of demand, is now being incorporated into behavioural demands and environmental requirements of farm animals. Laying hens have been found to have an inelastic demand for various types of floor litter such as sand, peat or wood shavings. The demand of other types of litter, feathers and straw, have yet to be studied, thus this study set out to determine the elasticity of the demand for the said types of litter. Every second day for one hour, the hens had to peck at a key a certain number of times, after which they received a reward, access to either straw or feathers. All the laying hens were willing to work for access to straw, while only three were willing to work for access to the feathers. Dustbathing was not consistently performed in either of the two types of litter. Even though the hens did not use the access to straw to dustbathe, the study still found that they have a high demand for access to this form of litter.
