Different kind of tick. I have deer ticks that carry Lyme disease to pets and people. Including me.https://www.backyardchickens.com/threads/ribhs-dcoopage.1295189/page-1479#post-23284814
I'm not sure what sort of tick you have @Marie2020. Our most dangerous ones are paralysis ticks. As you can see on Luna they get in really hard to remove places. I had a cat who always got them on the rim of his eyelid. Ever try removing a tick from a cat's eyelid? It can't be done. A little vaseline or similar smothers the tick. They can't breath & immediately begin backing out of their victim & eventually just drop off dead. I've never heard ours pump all their venom into their victim before dropping off. I have heard the opposite but can't say for certain. I'd check with your wildlife people. All I know is I've saved lots of animals this way. Using tweezers you're likely to squeeze the tick & that will put venom in the victim.
