Enjoy your chicks, they will become more than 4, chicken math.
I wish I had a bigger coop to begin but of course, I was only going to have so many chickens. Well that first coop was full by the end of the first summer. Our second coop, built a year later is 8'x8'x9' and is already full. I'm going to need to expand the first coop or build another (shhh, don't tell my husband

). Oh and Plenty of ventilation.
