Ok thanks for letting me know do you have any recommendations on good natural deworming or any dewormer in general
I use Valbazen sheep dewormer
The dosage is about 1/2 a ml for a 5-6 pound hen, or a 0.08 ml per pound of body weight.
Almost all of my chickens weighed differently (at the time some were 12 weeks, others were 1 year, and others were 3 years, plus some were bantams.) I wrote down their weight (I placed them on a kitchen scale covered in plastic wrap) then calculated how much to give them, then gave them the dose. With a flock of 13, it took about 2 hours to do it all. (I gave them a lot of mealworms as a reward.)
You give it orally with a syringe, opening their beak with two fingers pinching the sides, (some people say to pull on their wattles, but I don't do this as it sounds more uncomfortable and some of the 12 week olds didn't have wattles) then squirt it down their throat. I find it best to have a helper for that. It wasn't cheap (about 60 dollars, but its a big bottle) but I probably won't use most of it. It's not natural, I don't think though.
This is what I used (not my photo) I like it because it is very gentle, but works really well. Some people say to discard eggs, but I ate them fine afterwards. If you're worried about someone in your family having a reaction to something in the medicine, I would toss the eggs, but I didn't.
