<P> Legal standards defining "free - range" can be different or even non-existent depending on the country . Various watchdog organizations, governmental agencies and industry groups adhere to differing criteria of what constitutes "free - range" and "cage - free" status . </P> <P> The U.S. Department of Agriculture (USDA) requires that egg producers be able to demonstrate that "free range" egg layers have access to the outdoors, though there is no government oversight as to the quality of the external environment, or the amount of time the hen has access to it . Many producers label their eggs as cage - free in addition to, or instead of, free - range . Recently, US egg labels have expanded to include the term "barn - roaming," to more accurately describe the source of those eggs that are laid by hens which cannot range freely, but are confined to a barn instead of a more restrictive cage . </P> <P> Cage - free eggs have been a major cause of debate in the US . In 2015 there was a proposed initiative that would ban the sale of in - state meat or eggs "from caged animals raised anywhere in the nation". This shift from caged to cage - free is concerning for egg industry groups because they believe that this will cause the price of eggs to increase to the point that consumers cannot afford to buy them, thereby causing a decline in the egg industry overall . Animal welfare advocates argue that costs will not change as drastically as industry groups are expecting and that the price of eggs will remain almost the same because the housing of the birds does not make a huge difference to cost . Egg industry groups are making an effort to show or "educate lawmakers, voters and consumers about the merits and cost - effectiveness of cage use". Local farmers and producers say that the shift will occur if that is what consumers want, they will adapt to having birds in or out of cages . Not only are there debates between the egg industry and animal welfare advocates, but people are also debating whether this issue is one that has to be handled by the federal government or the industry . </P> <P> In the EU, cage - free egg production includes barns, free - range, organic (in the UK, systems must be free - range if they are to be labelled as organic) and aviary systems . Non-cage systems may be single or multi-tier (up to four levels), with or without outdoor access . In the UK, free - range systems are the most popular of the non-cage alternatives, accounting for around 44% of all eggs in 2013, whereas barns and organic eggs together accounted for 5% . </P>
