1. Laying hens showed a clear preference for maggots over whole grain wheat, feed pellets and other food stuffs in a preference test. 2. Motivation to work for maggots in an operant conditioning task was high and unaffected by periods of food deprivation of up to 6h before testing. 3. By extrapolation, motivation to work for maggots was equivalent to the motivation of the hens to work for their normal ration after approximately 9 h food deprivation. 4. Food deprivation is a common prerequisite for laying hens in operant conditioning and other behavioural techniques but can be avoided if an attractive food, such as maggots, is used. The mild distress associated with the deprivation is thereby removed and, in the UK, the procedure would not require regulation under the Animals (Scientific Procedures) Act 1986.
