I can relate. We used to keep numerous "barnyard" flocks that usually had other livestock and dogs about. Such locations also had cover birds could retreat to and a very, very capable rooster. Loss to Red-tailed Hawks was very low as was losses to predators in general.
In current location I had to reboot operation which is when I had to experience the joy hawks and others stealing birds. Free-range chicks where taken out by Coopers Hawks until a rooster was put out with them which shut that hawk species down. Broody hens also help with really small chicks but once weaned the young birds need to be a month or more older before they are too large for Coopers to take. During that interval rooster provides protection. Red-tails usually do not hunt my ground during warmer parts of year because Red-shouldered Hawks work area at that time and they do not pose a threat to chickens. During the winter with lots of snow is when Red-tailed and even Ferruginous hawks briefly posed a problem. That was compensated for in part by moving feeding stations to areas with more cover and penning more vulnerable birds (American Dominiques). First dog came into picture about that time which really put a nix on such hawk activities as he would run to chickens making alarm calls and go after hawk. I encouraged that. Over last three years I have had more small juvenile chickens out than I can protect with roosters (best anti-hawk roosters fight too much with each other) so second dog was brought into picture and pens were dispersed so hawks would see larger chickens where ever they saw vulnerable young birds.
Also hawk abundance varies from year to year. Some years I can see a hawk working ground multiple times a day, other times maybe once a week. Hard winters usually mean fewer hawks following production season. For me, hawks are not looking first for chickens, rather they are usually after smaller game and chickens prove to be targets of opportunity. Exception to that involves Coopers Hawks going after chicks.
If you do not have protection, then at some point a hawk will find you and hunt your birds for a while before moving on. Ten years is not that long of an interval.
