Hello all, I'm just getting started with chickens, I have decided on Barred Rocks as I am looking for both egg and meat production. I am wondering (among other things) about flock separation, my plan is to build a coop/run for the meat birds, remodel the chicken coop in the barn for the layers, and keep a section for the rooster(s). In the end I want to be able to produce my own chicks two or three times a year to grow for meat as well as replace layers as they drop in production.I have room in my planned coop for 50 meat birds, the run will be 35' x 45' divided into 2 sections so I can alternate which they are in every week or two weeks, and am planning on 12 layers. Feeders and waterers': I am going to make J-tube feeders of 3" or 4" PVC, and waterers out of 5 gallon buckets. How many birds per feeder? How many birds per waterer? For the replacement birds I am looking for advice on what a good brooder hen would be, or, should I try to pick one out of my flock? Do I need a different coop/run for the broody and the chicks or can I keep them in with the layers? For the layers, in addition to the boxes, do I still need roost poles? I have more questions, but will try to find answers in the forums as I need but these are the most pressing as I will be ordering and building/remodeling coops and runs soon. Thanks!
