I recommend that you DO NOT worm routinely. Worming irritates the lining of the intestine and weakens the immune system. So, in my opinion which I believe is based on sound reasoning and research - I would only worm if you know there is a problem. (This could be confirmed with a stool sample to a vet for a very reasonable price usually.)I am still reading this thread from the beginning, which is taking a while, so my question is about worming. Do it or not and if so how and with what? I have 43 chickens ranging in age from 2 weeks old to 2 years old. BTW really enjoying this thread! Thanks
If you have sound husbandry, good feeding and housing that isn't too crowded, and the ability to range some, you will likely never need to use a wormer. In NATURAL CHICKEN KEEPING, the focus is on PREVENTION rather than TREATMENT.
[FYI...the "Chicken Health for Dummies" book which was co-authored by the owner of BYC also cautions against "routine worming" as well for the same reasons. And that book isn't necessarily coming from a "natural" approach.]
That being said, there are some good, more "natural" alternatives for worming that don't upset the system quite as much as the chemical wormers do and really do work wonderfully.
If you do find the need to worm, the next job is to try to figure out what is causing an environment such that they are in that condition and, if possible, fix the cause.
Also...
Sometimes a particular chicken is weak for whatever reason and does not have good immune response. On occasion you'll find one chicken in a flock that is weak and the ONLY one that has issues in the whole flock. In that case it is likely the time to cull, unfortunately. If you have a whole flock of healthy, strong chickens and one is continually weak it is "usually" an underlying issue with that particular bird.
Edited to fix a typo!
