Quote: I am lucky to keep about 30% of what I kill, the other 70% have mange really bad. Anyone know what causes it to get this bad ? About 5 to 10 years ago they were all good pelts, now it is crap ! Kevin Mange spreads from one coyote to the next by way of either direct contact or indirect contact such as a healthy coyote sharing a den with a mangy coyote. Until you kill all the coyotes with mange, the disease will continue to spread.
Around my family's farm in KS., we went through a long period of time with next to zero healthy coyotes, but these days it seems that the disease is almost run it's course and most coyotes are looking healthy again.
In my area here in Colo., it seems the mange is just getting a foot hold and I suspect it's going to get worse before it gets better.
