Good evening from San Jose, California. I am new to chickens, and will start my flock this coming May when my daughter's pre-school hatches their eggs! We have wanted them for years and now have a perfect situation to begin our flock. After doing a bit of research, I would like to get Orpingtons as I understand that they are great with children and are very smart. I understand that they get about 10lbs and want to be sure that they have enough space. The hope is to have 3-4 hens. The dimensions that we plan on using for the coop and run are shown below. Please let me know if you think this is sufficient space for these dear animals, as I really want to do right by these birds. COOP- 4'x4'x6' with an external nesting box NESTING BOX- 12"x12" RUN- 7'x8' and tall enough for a human to walk in Thank you for your thoughts.
