That describes my flock other than in the winter. Snow isn't very nutritious and my girls don't go out in it.In places where forage is good they'll forage in the morning for a couple of hours and then look for cover and rest, making occasional trips out to find a bit more. Then in the late afternoon they'll attempt to fill their crops for the night.
In the winter they have a full feeder in the coop. Their auto door opens with daylight so the have access to the lower part of the barn until I open the outside door. In the non snow months I toss a jar of layer pellets outside when I open the barn and they go at it. Then they forage as they like all day. Mid-late afternoon the get another jar of layer pellets tossed. They put themselves in the coop (well most of them do) as it starts to get dark and once I know everyone is inside (some with assistance) I close up the barn.The advice to always have feed available comes from an understanding of a chickens digestive system but ignores the keeping circumstances. So yes, for chickens confined in a coop and run having feed constantly available is necessary but for free range chickens it's often not necessary; they will forage enough to keep food in their digestive system.
I get the occasional "from the roost" egg. They usually survive the 4 foot (1.2 meters) drop, I've got "deep bedding".I have had hens lay in the middle of the night but not from the roost.
