This study was aimed at comparing production results of laying hens kept in two types of cages: furnished cages and conventional cages. It covered the period from the 36th till the 54th week of hens life that was divided into two experimental stages: stage I - from week 36 till week 44, and stage II - from week 46 to week 54. Till week 44, 190 layers were reared in groups (10 hens each) in furnished cages (F) and 190 layers were kept individually in conventional cages (C). In week 45, the hens from furnished cages (F) were moved to conventional cages (FC), whereas these from conventional cages (C) were randomly merged into groups of 10 hens and transferred to furnished cages (CF). Egg laying (%) and egg weight (g) were controlled as well as percentage contribution of eggs in standard egg weight classes was determined in both experimental stages. The study showed a significant (P < 0.01) effect of cage type on the laying performance of the hens but only in the second stage of the study, as well as a significant (P < 0.01) effect of hens moving to different cages. In both cases, higher egg laying was reported for the hens from the conventional cages. Egg weight in the first and the second stage of the experiment was significantly (P < 0.01) higher in the groups housed in the furnished cage. A higher egg weight (P < 0.01) was determined in the layers in the second stage of the study. Both in the first (P < 0.01) and in the second (P < 0.05) stage, analyses showed a significant effect of cage type on the contribution (%) of eggs in particular egg weight classes. A higher percentage of eggs in the L class was obtained from the hens housed in the furnished cages. Differences in laying performance after hens moving suggest that the layers adapt more easily and faster to conditions of the C type cages. The egg weight was, probably, more dependent on general laying performance and age of the hens than on cage type.

Modern broiler chickens are genetically selected for reaching higher weights in shorter life spans. In addition to this, they are raised in crowded housing conditions with less opportunity for movement. Understanding movement patterns, migration and use of space is essential in determining welfare of the birds in commercial farms. In this study, migration behaviour of broiler chickens in semi-commercial farms of 1800 chickens was studied. Observations were repeated in six growth periods each on 12 chickens once a day during their growth period of 42 days. It was seen that the activity of broilers was not decreasing during the growth period. Travelled distances of the chickens in total were not reduced in the last 3 weeks of their growth period (p > 0.05 in 89% of the observed birds, Mann-Whitney U test). Chickens preferred to be in the zones next to the wall farthest to the entrance of the house. The observed birds did not restrict themselves only around the feeders and the drinkers but used the whole surface area available during the whole growth period. The results of the study seem to be encouraging in achieving welfare of broiler chickens even in commercialised houses with high stocking density. Reported mobility of chickens is important for their survival and has therefore considerable impact on efficient production on farms.
