The government is asking the public whether they think the cages are cruel. If we say yes, they might get rid of them one day.
Farmers can't use old battery cages from 2012, or build new ones from 2003.
But they can still use 'enriched' battery cages, which have more room for the hens, a nest box, perch and litter.
Some countries like Germany have decided to ban these better cages too, because they still think they're cruel and cramped.
Animal groups like the RSPCA think all these cages are cruel, but egg industry bosses say banning them won't do any good.
They say the UK will be forced to buy cheaper battery hen eggs from other countries instead.
