Two feet high is (maybe) OK for meat birds, but not for layers. There would be no space for roosts (their heads would already be near the roof when standing on the ground). Meat birds who will be sent to freezer camp by age 10 weeks do not need roosts, but layers, who you hope to keep for at least a year or two do need roosts. Nature has taught them to not sleep on the ground, but as high as they can. If they have to live on the ground, they will be stressed, and unhappy...a sure recipe for low egg production. If they cannot feel safe, their desire to reproduce will be greatly diminished. A stressed hen has more acidic juices in the stomach/innards which greatly compromises her overall health.
Seasons also factor into the equation. Summer time requires good air space to keep it from overheating and provide good circulation. Winter time also requires good circulation, and don't forget that in bad weather, they may be confined for weeks at a time.
California recently had to (early) release 10's of thousands of prisoners because Federal regulations deemed that they were too crowded. Don't let your hens live in worse conditions than a man on Death row is entitled to, please.
