Are the foxes dieing of starvation then your saying? What is your guess of coyote population in your state?
No fox probably aren’t starving to death just like few deer actually starve to death. But, starving isn’t always the way nature reduces a wildlife population to keep it within the limits of its food supply. The more typical method of limiting wildlife populations is with lower reproductive rates or recruitment rates that fit the availability of the food supply.
I don’t know how many coyotes we have but the number really doesn’t matter anyway. They are here in all areas with suitable habitat and have been for a long time.
Here is a link that should help you become better informed on coyotes and how they function in nature.

What evidence do you have in the decline of coyotes because the increase of bobcats?
Besides personal observations also by being a Conservation Officer that monitors wildlife population trends by using volunteers that travel designated wildlife survey route each fall. As those volunteers have recorded increasing bobcat numbers they have also recorded declining coyote numbers.
Most the time coyotes run in pairs or more. I would think they would attack a bobcat just to kill it as they do foxes.
Again they are protecting their food sources from other predators.
That is an extremely rare occurrence. Read the above link.
They killed 22% of the fawns that are born. That was when your deer herd numbers was high. Now when you lowered your deer herds,What % of fawns for re-population won't make it thru the first year?
Predation by any species was very low in the study area where they had suitable deer habitat and extremely high where the deer habitat has been degraded from year of high deer population.
Here is a link to the fawn study mortality facts.
