On our farm we have an old hog barn that we don't use anymore it was just sitting empty until last year when I put 25 chickens in it to be raised for meat. It worked ok and now we are thinking of getting more to put in there this summer. The barn has heat and a few fans to control temperature it has a slotted floor for the waste to fall through. There are 10 pens each is about 5x10 feet and last year the chickens stayed it the pens and didn't fly out. I am new to raising chickens so my friend helped me out this year I will do it myself. Here are some questions I have. What feed should I use? What breeds would be the best for me? Last year I had Cornish crosses. I think Ways to reduce costs? Do I need some sort of bedding? Do I need to let them out to roam around?
