Time of year seems to affect the "worst predator status. Fall/winter we seem to have more problem with the hawks. Summer it is a whole lot, hawks, coyotes, foxes, raccoons, dogs that the owners swear it just couldn't be "fido" when they are left out to run all day when they are at work ( we are having some major problems with the dogs in the sheep). Also, oppossums. We have an eagle that has been preying on a neighbors' boer goat kids (40 lb size). Owls seem to be more active in the spring/summer. Spring seems to be more of foxes (with dens). Does it ever end??????? Feral cats. There is a neighborhood bobcat that has been seen by several people early in the morning, but I don't let the birds out until after 10 or so , so he has not bothered them. The hawks are the worst to get control of, as you can trap, shoot, or even poison most everything "legally", but the winged predators.
