Supposedly, guineas will rid a property of ticks. I can't personally vouch for this as I've never kept guineas. I plan on getting some next spring. But everyone who's had them tells me that they will eliminate ticks.

We have three species of fox here: red, gray and kit. I've never lost birds to a fox altho last weekend a little kit fox was trying to get into the coop. I have lost birds in previous years to the bobcat, raccoon, long-tailed weasel and sharp-shinned hawk. Now my birds are more secure in the coop and chicken tractor. Turkeys, ducks and geese roam free during the day but are confined at night. The chickens are never free because they are too hard to catch, but the tractor gets moved every other day so that they have new greens & bugs regularly. One of my white turkey hens recently drowned in the small pond the ducks & geese use. I guess that she thot the white ducks were turkeys and that she could swim too, if they could.
