Abstract
Battery-kept hens (Sykes Tints) showed a preference for a large (0.76 .times. 0.86 m) over a small (0.38 .times. 0.43 m) cage but preferred the smaller cage when this had a litter floor to the one 4 times larger with a wire floor. The hens still showed a preference for litter when they could obtain access to it only by entering an even smaller cage (0.38 .times. 0.215 m) in which they could hardly turn round. This cage gave far less space than that recommended by the UK Welfare Codes (1971). Increasing the space allowed to battery-kept hens may not be as valuable to them as giving them access to litter.
