Mine free range all day from when I go out to open up the 2 coops which is before I get on this addictive forum( or they wouldn't get out til noon) until just about dark when I go back out and close up the coops.
They put themselves to bed where we just have to lock up but if we go out too early they see us coming and come running expecting treats.
The 2 flocks mix during the day but go back to their separate coops at night.
They range over about an acre of unfenced yard,horse corrals, mowed pasture and porches where they clean up cat food that got left behind but leave deposits that we have to clean up.
The cats are loose with them and only occasionally do we see a cat chase a chicken but once they are up in the air the cats lose interest. We have never trimmed wings to allow the chickens the ability to escape vertically along with horizontally.
We have lost 2 chickens from drowning in the swimming pool, well one froze but have rescued others with the pool net after they got in the pool. We know they are in there when we look outside and see the cats lined up around the pool intently looking inward.
We are on the edge of town and have minimal daytime predator problems, occasionally a dog or a hawk but the chickens have trees or shrubs for cover.
Feed is scattered around the yard near the coops but they roam most of the day looking for other things to eat. There are several water containers around the place and all the animals and chickens use them.
Most of the eggs are laid in the coops but if the count varies drastically for a couple of days then we look for a secret stash which normally is used only for a cople of days if we keep retreiving the eggs.
