If you have mongoose, cats, etc. I wouldn't. But ...
I had a large flock I used to coop up in Ft Knox, with free-ranging during the day in a 1-acre backyard. For various reasons (fencing, my dog, etc) I pretty much quit worrying about predators after about a year and started leaving the coop open. I didn't lose a single chicken to predators (well, a flighty free chick disappeared, but that was before I started leaving the coop open and I suspect she flew away). I DID have my heavy regular layers laying in a few spots in the yard. When I briefly tried locking them in at night to break the habit, they just held the eggs till I let them out later in the day. I decided it wasn't worth it and let them lay in their chosen spots.
Hens prone to broodiness are another matter. All my bantams would get broody and sleep on their nests, even with eggs removed. I never lost any. One persistent girl left the yard to hide and in hatch her eggs and didn't come back until she had chicks. THOSE chicks refused to sleep in the coop at night and remained semi-wild. My other laying hens never abandoned the coop for sleeping. All went in, every night. Could have been partially thanks to my roo though, who kept pacing till they were all in and then he went in to roost.
But ... With those predators and no other protection, I wouldn't.
