We purchased our first flock 9-10 weeks ago. It consist of several breeds of chickens, 4 bronze turkeys, and 7 guineas. We have 15 acres and no close neighbors. Eventually we plan to add cattle and sheep to our farm. We already have goats dogs and cats. My question is we converted 1/4th of our barn into a fully indoor enclosed chicken coop. The entire coop is about 40 by 30. We were planning to add a 40X40 outdoor area that is fenced and covered to protect them from any predators. My concern is with having 15 acres I really wanted to allow them to free range. Would love if they would roam around the property during the day and return to their safe coop at night. What are the pro's and cons of each way? Also if I were to allow them to free range at what age would be ideal to let them out for their first time? They are 9-10 weeks old (all of them we tried to keep the turkeys guineas and chickens very close in age) Should I turn them out in the morning and let them roam until evening and try to lure them back into their coop with food? Or would turning them out for just a few hours before dark be better? I just want the best for them and I feel like being contained to a 40X40 area as their "outside" space is not good enough when we have 15 acres they can explore. Also I plan to add milk crate type hen boxes to the inside coop. What would be the ideal thing to use on the flooring on the inside coop? Right now the entire floor of the barn is gravel.
