Abstract An experiment was performed in practise, where chicks were monitored that hatched at the farm using the One2Born concept with respect to hatchability and the presence of E-coli and ESBL producing E-coli. These results were compared to the traditional system where chicks hatched in the hatchery and were subsequently transported to the broiler farm. Embryo survival, escape possibilities of chicks from the One2Born hatcher boxes during transport, the presence of E-coli and ESBL producing E-coli bacteria in the hatchery and at the broiler farm were investigated. Also observations were made of hatch moment, chick temperature and crop filling. Embryos in the One2Born concept had a 1% higher survival rate than hatchery chicks. ESBL contamination at d7 in the broiler farm was the same for both groups. In this experiment vertical transmission of ESBL producing E-coli bacteria was more likely than cross-contamination of ESBL in the hatchery. 95% of all One2Born chicks hatched within 24 hrs. Chick temperature measurements and crop filling rates showed the importance to consequently measure chick temperature and for action to adjust house temperature accordingly.
