Hi everyone! One thing I don't know much about is parasite control. I've read differing opinions and wondered what you all do. My chickens run around outside all day long eating worms, bugs, and digging in compost. We got them in the spring. Should I routinely treat them for worms? If so, when and how often? What is best to use? What about mites & lice? Do you routinely treat for that or wait until you see that you have a problem? Thanks in advance!
