Very cute and you're off to a great start. Just a couple of suggestions; chickens want to roost/sleep on the highest point they can get to so be sure your roosting bar(s) is/are higher than your nest boxes, otherwise they'll be sleeping and pooing in the boxes and nobody wants that. It does look a little small for the number of hens you have so you may also want to consider putting an addition on your coop. The typical recommended space inside the coop is 4 sq ft per bird and 10 sq ft per bird in the run. Not having enough space can lead to poor health and bickering and the bickering can lead to injuries and even cannibalism. Catch trays under roosts are also a huge help. Chickens poo the most when the sleep so by having trays underneath the roosts to catch it all making for quick clean ups and saves on the cost of bedding.
