Effects of housing systems and laying phases on external and internal egg quality characteristics of indigenous guinea fowl hens.

The study investigated the effect of housing system and laying phases on the internal and external qualities of guinea fowl eggs laid in three different housing systems. The trial involved the use of 117, 34-wk-old guinea fowl hens which were assigned to three housing types, which were battery cages, deep litter, and deep litter housing systems with free runs, which had the same dimensions as deep litter houses but with free run and open-air space to allow the birds to have free access to soil and exhibit natural behavior. The laying phases of the birds were partitioned into three (36 to 40, 41 to 45, and 46 to 50 wk of age).
