I am just now starting to read about chicken getting worms, I am glad I found your thread. I had some of the same questions.
I live in Ohio; I am a new chicken owner, only having raised my chicks since May of this year. I have not medicated my chickens for anything thus far other than the medicated feed recommended for baby chicks. This past week I just started them on the round of recommended store bought feed.
I live in the suburbs and only let my chickens free range for about one to two hours a day, I use a sand base in the chicken enclosure. One side of the enclosure the sand stays nice and dry. The other side of the enclosure is exposed to the weather more often as is off and on wet and dry conditions.
I will take the advice on this post and seek out the products you posted and get my chickens on a de wormer regiment.
Questions - Does wet sand pose the same threat as wet soil when it comes to conditions for worms?
Question – Are there any other medication I should be administering to my chickens on a regular basis for disease prevention.
Also - I was listening to a chicken whisperer pod cast yesterday, the subject was on backyard chicken owners both medicating and/or the lack of medicating their backyard flocks for disease control.
They did not specifically say what should be administered or not, the discussion was more on the side effects of medication and the trace amounts of medication being found in the eggs produced by the chicken being medicated.
Question – When I do start the worm medication should I be concerned with the eggs from the medicated chickens?
