I had not wormed my chickens in 3 years mainly because they act healthy and the plant, wormwood, grows wild in their pasture. Lately, I have seen some roundworms in my poop inspections, so am in the process of worming everyone with Valbazen. It is a big process on over 100 chickens, but hopefully it will take the count down to zero for a while. Second dose due Wednesday.
They have started eating like there is no tomorrow. IDK, if it is the cooler weather, the decrease in worms or that they are molting.
So if the plant "wormwood" was an effective de-wormer, why would you be seeing large roundworms? Glad you are able to treat the flock with Valbazen, I know that is a *huge* task.
