This makes a lot of sense to me. I was thinking that 100yrs ago, what did they do?? Our winters are very mild, we might get .5 of snow if we're lucky (my kids live for that one day a year lol) and an occasional ice storm. We're going to have 2-3 cows and 2-3 horses and a flock of chickens, It would seem to me (though I have no experience) that the chickens should be able to manage okay if there is a good amount of acreage. We're still in the research phase but, we are planning to separate the acreage into small paddocks and rotate the livestock through on a daily basis, I'm thinking the chickens could be a day behind the cows so they scratch the manure in and can pick out any parasites in the cow patties. They'll be shade trees through out so the animals can seek shade through out the day. Heat is more of an issue here than cold with summer temps frequently at 110* They'd be cooped at night and I think we'll probably have a couple of dogs to watch over it all. I figure we'll have some hay in the winter for the cows and horses and couldn't the chickens be in the barn with them if the weather is bad? There again benefiting from the insects that accompany the bigger animals and the hay bits left behind.
