Lehmann, M. 1987. Interference of a restricted environment - as found in battery cages - with normal behaviour of young fattening rabbits. In: Rabbit Production Systems Including Welfare. Auxilia, T. (ed), 257-268. Official Publications of the European Communities, Luxembourg, Belgium.

Single-caged rabbits were not able to hop in rabbit-typical fashion; they were less active but more restless [frequent activity changes] and showed more stereotypical gnawing of the wire cages than group-housed animals. It is evident that space, but also shelter and occupation opportunities are important for young rabbits to show undisturbed behaviour.
