I have seen wolf pee advertised. I am unsure about Colorado but I have killed coyotes almost every year while they were hunting in the daylight. A rooster will call one up crowing just like a turkey. You may not have had one killer but two or more. I have seen coyotes together more than fox.
Lol I guess I should say I don't know about coyotes anywhere BUT Colorado ha-ha

Sure, they come out during the day, all the time. However, they are pack animals, and they HUNT at night. They won't come within 100 yards of the place during daylight here, where a fox will run right through the garden while I'm IN it

At night, however, the situation changes. The coyotes howl to each other within FEET of our back door, and will tear into trash if they can't get into the coops or barns because of the dogs..
Dogs are just about the only way to really and seriously keep coyotes or foxes away. Really, any predator can be deterred by a good guard dog. And even then, there are no guarantees...
On the urine.. I use urine to ATTRACT furbeareres, never to repel. But I've read of some people that try it, not sure if they could stand the smell though

So now I"m wondering if it was a fox. Today I saw them running like they were chasing something. So I go outside and couldn't find my goose. I went into hysterics for about 20 mins til I found her in the fenced in pasture. She has never been in the pasture before...never because she killed my silky bantam rooster. Anywaaaay, I thought she was dead. I'm surrounded by fields of 7 foot tall grass so I couldn't see where they were going but finally I saw her standing beside my goats. I hugged her in relief. She thought I was crazy. lol She had to fly to get over the fence. What a relief that was!
