So, the supportive responses here are very appreciated. I was similiarly grossed out and now am just examining all the poops tooDown their throat. Have someone hold them and pull down on their wattles. It opens their mouth. Shove the oral syringe in there, squirt.
We do it early in the morning before we let them out of the coop, and after we worm them we throw them out into the run so we know we got everyone. It takes some time, and there's a bit of anarchy (especially for those birds that HAVE TO LAY AN EGG NOW MOM!) but it works. What didn't work was putting the dose on a piece of bread (a common helpful hint from other people who worm) because they start fighting for the bread and some only get a small piece of the dose. Wattle pulling is totally the way to go.

What is waddle pulling??
I read to use Safeguard on the chickens for worms.
Bucka, fox are creatures of habit. If they are on your property once they will be again unless you can disrupt that habit. Especially in spring when their kits are waiting in the den and nursing momma is starving. They will come at any hour of the day if they have had a taste of food or it looks like they will. I have had a number of older chicken and fowl keepers swear by their red eye machines but I still don't have them. If you see that fox again I would run out there and look loud and scarey again just to try to make a statement a few times about 'not here.' It will try at other times of the day to see if you aren't home then so you might want to leave the chickies in for a week. Pick grass for them if you have to. I have a son who pees around the coop and a dog who does the property perimeter. I think that helps too.I went out onto the porch and the fox ran off about 15 feet, and then stopped and turned to look at me. I ran towards him and tried to look threatening (ha), and he did leave for now, but I have the feeling he'll be back.
Meanwhile, I have 12 week old chicks in my carport. That is not so secure. I wish DH wasn't working so much because I need to get them into the hoop coop.
