Yes

The legal definition of "free range" is only that they have
access to the outside, they don't actually have to go outside. It doesn't say anything about how much space nor length of time. The "outside" could be a 2 sq ft concrete pad with the door open 5 minutes a day. In fact, anyone who has a run outside a building is raising "free range" chickens since they aren't confined to a building full time.
There really is no legal description for what many here are doing. Having full day access to 20 acres of pasture doesn't make them "pastured", those birds are often in "tractors" on a pasture rather than in a coop. The tractor is moved daily to the next patch of pasture.
I applaud you for checking on them but have a warning. If a fox can get in, it takes maybe 10-15 seconds for it to snag a hen. When I had 6" field fence a fox came through it in broad daylight and snagged my best layer, a White Rock, right behind the barn. I found only a trail of feathers.
Later that day as I was coming out of the barn the chickens came running with a fox right behind. The fact that I happened to be there RIGHT at that time saved another from being taken. By the time I got through the gate, a mere 5' from the barn door, and out 10' to see where the fox was it had made it 150', through the fence and was standing on the road that runs up the hill beside our property. After that the fence was "amended" with 2x4 knotted wire fence.
I had no idea that a fox can get through a space smaller than 5". A coon can get through much smaller spaces .... but not 2x4
