Just bought our first home! Were on about an acre but in the mountains were it gets pretty cold in the winter. There are a couple good garden areas that get good sun and we'd like to have a chicken coup where they'd stay secured at night but be able to free range during the day as we would definately have to worry about preditors. About a dozen eggs a week is what were looking for. Would like to know what kind and how many we would need that fit our needs. We have small kids and a cat and are looking to get a dog as well. They must family/animal friendly and dont mind temps down to 20 degrees a few times in the winter. Any advice will be much appreciated.
