Hello, We are working on building our first coop and have started researching breeds to start out with. I have my eye on a few, but what would you all recommend? We live in the city, but they will have a run that is about 10ft. by 5ft and if the dog adjusts well, free run to our entire yard for most of the day. We have 3 kids, 9, 7, and 2. I am looking for good layers, preferably brown eggs. Because we are in the city, my biggest concern is noise, not sure if some breeds are "quieter" than others. Plan to get 3-6 hens depending on the breed size I decide on. Thanks for your help.
