It is a bit tight, and if there is tension in the flock, you really should reduce some birds.
People often talk about free ranging as making up for a lack of space in the coop. In the summer you can do that, the days are long, and the nights are short. The birds are OUTSIDE for most of the hours in the 24 / day. However, this time of year, mine are roosted up earlier and earlier each day. In a couple of weeks, even on really NICE days, they will be headed in by a bit after 4:00 and be staying there until daylight the next morning. To me, this time of year, you really need to look and measure your roost space, and count your birds.
I had a tight number like that one time, and lost two birds to a predator. Felt bad about it, but quickly noted that my flock seemed much more relaxed. They were happier, there was less squabbles. I don't think you would be asking, unless you are picking up on the tension in your flock.
