I’ll try not to repeat what’s been said too much. I had to stop free-ranging, because they were going over to my neighbor’s across the road. Turds. What helps is letting them out only a few hours before dark and making sure I have a flock block (chicken candy) by the coop.
I don’t feed in the coop unless it is raining. For water, I use a rubber feed tub in the winter (galvanized waterer in the summer) so I am forced to go in there every day to stomp the ice out and give them clean water.
I deep bed with horse shavings. I wear a respirator to scoop out the coop. Bird poop can be very bad for your health.
My coop and chicken run/tunnels are in my blog.
I haven’t had any roosters on purpose, but I’m thinking about it. I think you need a fair amount of hens for a happy hen house with a rooster.
I trained my dogs not to eat the chickens.
