Much too small, unless they are bantams. In general, you should have about 4 sq ft of coop space per bird and about 10 sq ft of run space per bird. Some breeds need more than that though. Barred Rocks, for instance are very inquisitive birds that have a tendency to get bored with coop/run life. That boredom can lead to aggression issues.
looks like might have to add in an extension later... but for now they will mainly stay in here and i'll let them out to roam the whole yard for 30-60 minutes when i clean the run/coop
honestly, i don't know which breed my chickens are
these are my chickens. Thanks
