I have too many chickens :). It can be daunting, but it can also be done. I would love to free range my hens, but we have a hawk in the yard, foxes that trot through in the daytime, and coyotes in the evenings. Heavy predator action! My girls have a coop that allows for 4 sq feet per hen and a small run - only 5 sq feet per hen. But it's very fortified, with three feet of concrete foundation and hardware wire. The lower half has hardware wire and will get additional goat wire this weekend. Outside there is 3 feet of welded wire going out from the coop to prevent digging predators. We also have a roof. Inside the coop, we deal with overcrowding by using lots of roosts (2x4's, 2x6's, logs, a tire, rocks, etc). I pick up poop twice a day from the coop and run. They get cabbages and other veggies in hanging holders and suet feeders. I have food and water in the coop and in the run so no one is pushed away. There's a sand pile and a dirt bath area. The coop has floor space, a 2.5 foot x 12 foot shelf, and 30 feet of roosting space - we put roosts in front of the windows also. It's definitely more high maintainance to have a heavy load of hens, but my hens are happy - no picking at each other, shiny and healthy, no worm load. I use DE and also give them brewers yeast, probiotics, herbs, oatmeal, and BOSS in their feed. They get a very high quality scratch in the evenings and various tablescraps. We are building a moveable cage that could house 4-6 hens during the day to move around the garden. We also have a 6x12 foot dog pen that the hens can hang out in, but only if we are with them. I usually spend 1-3 hours a day with them. Love those chicks!
