I don't know where in Ohio you live, but north of Akron, we have a pack that crosses the back of our property following the deer. The male weighs in at about 80 lbs (and is very dark- like the black phase that Woodmort mentioned) he is huge, the females in his pack seem to be about 40-50lbs and are much lighter. They could weigh less, depending on how thick their coats are, but the male is bigger than my wolf/husky mix, and she goes 65 lbs. I talked to a CVNF ranger last summer and was told that our coyotes have cross bred with dogs, which is why they are so large. So far I have seen some tracks around my coop, but I think they are fox- very small. Keeping my fingers crossed that the coyotes will stay on the other sice of the ridge and not bother the chickens. As far as I know, none of my neighbors have lost chickens to coyotes, so I hope you can keep them out of your coop if they are trying to find a way in. Laura
