It may anecdotally expel, which is great - but it's still not yet proven to do so, so I'm always careful not to guarantee something that they can't (yet) guarantee themselves.
Tests are pending.
I'm curious though - did you do a fecal egg count before that showed a heavy infestation of parasites? (I still recommend VermX, but a certain way - so even anecdotal information is very useful).
Figured this was a good post to add onto. I am posting this so I can make sure what I plan on doing is correct.
I am planning on starting a worming program. This is a preventative measure. I currently give DE in the feed. this will be my first time worming as only one of my chickens is over a year old and my youngest are just now 6 weeks.
My plan to remember worming is to perform the preventative worming every time there is a time change. It works for the fire alarm, figure it would work for this.
I'm going to use Wazine 17 a 16 oz bottle treats 800 chickens and only costs $6.50 here.
I'm removing the water Saturday night and medicated water will go in Sunday morning. I have 26 chickens. They never seem to go through more than a gallon a day, so I am putting 0.5 oz in a one gallon waterer. I will return regular water on Monday morning or late Sunday night.
all eggs for 2 weeks will be thrown away. During that two weeks I will give yogurt at least 4 times.
(I do have a question regarding the probiotics, can I get probiotic capsules that people take, open them up and mix them with the feed or possibly dust a pumpkin's inside with it as an alternative to the yogurt)
