Hi there, I am relatively new to backyardchickens.com and have 15 chickens. This is our first flock, and it has turned into more of an adventure than I expected. I also enjoy the chickens much more than I expected! We have 15 chickens: 5 black Austrolorp hens, 1 Rhode Island White hen, 3 Rhode Island red hens, 4 Barred Rock hens, 1 Barred Rock rooster, 1 caramel-colored hen. Their hen-house is spacious, and they have about 250 square feet of enclosed coop. Do I need to also allow them freedom to roam the yard once in a while? If so, how do I get them to go back into the coop? Our plan for next spring is to build an additional coop of the same size so that we can alternate their living space year to year. CLUCK!
