Regarding free ranging, because we are blessed enough to live on 36+ acres, we plan on fencing another portion in the spring and then rotate weekly...one week the chickens/guineas and eventually ducks/geese/peafowl will have access to the top pasture, while the dogs and goats/sheep will be in the bottom pasture. The next week we'll rotate. This will be beneficial for everyone as the chickens and guineas will eradicate the ticks in both pastures (great for the dogs and livestock) and they'll have a huge area to keep them healthy and strong. If only our dogs could see the birds as part of their charge, they'd all be able to have access to the entire property at all times. Alas, the dogs will protect the livestock and we humans to the death, but they cannot resist a scrumptious chicken dinner.
