Two story coop????

[rosemarythyme]

A question that relates to all this is -- how good are chickens at hopping and flying around in a narrow space? Is there a risk of injury if they don't have a large "landing zone" or if they fall off a high roost? Is it good to provide little ramps so they can reach all the high spots without neding to hop up or down?

Depends on the bird/breed. Smaller, lighter birds can maneuver pretty well. Big, heavy birds tend to just plummet with gravity.

Some birds will use ramps or hop down laddered roosts if provided, others will not. Two of my oldest hens will sometimes scream at me to come and physically lift them off the roost and lower them to the ground.
