<s>[INST] The next text is a question of a member of the European parliament:"Directive 2007/43/EC lays down minimum rules for the protection of chickens kept for meat production and seeks to reduce overcrowding by establishing a maximum stocking density and improve their well-being by ensuring that they have enough light, litter, ventilation and are inspected, as stipulated in Annex I.However, there is evidence that in some facilities the reality is quite different, with chickens cooped up in spaces with no ventilation or natural light and with inadequate levels of hygiene, such that they are prone to sickness and many die without having been attended to by vets.In the light of this and given the lack of regular inspections by vets, what measures will the Commission take to improve the scope of this Directive and ensure the well-being of chickens?Extensive breeding has been proven to be better for their well-being and the environment. Does the Commission intend to encourage the extensive breeding of chickens?"
