I am still in my first year of keeping chickens and I am wondering if I need to treat my hens for worms. I have a small flock, just four birds, and they all seem healthy, but egg production has definitely dropped over the past month. They are around 10 months old and have not been treated for worms before. I have read a number of threads on here about worming and still can't make up my mind whether or not to give my girls the chemicals. It seems like this would be the time to do it, since we wouldn't have to throw out as many eggs. I'm curious about taking stool samples to the vet to find out for sure whether or not they have worms. Any advice would be appreciated.
