SUMMARY

The production of antibodies from chicken eggs requires the housing of hens under laboratory conditions. Based on several years of experience, the accommodation of hens in modified dog kennels (for keeping on the floor) or guinea pig rack units (for keeping in cages) is described. The suitability of a commercially available hen's cage is assessed as well.

The three modes of accommodation are largely in accordance with the Swiss Ordinance for Animal Protection. Especially housing in pens provides an opportunity to the animals to behave largely according to their biological characteristics.
