Good day y'all, bit of an odd question and wasn't sure where to post it! I am currently raising a flock of 12 for pets, eggs, and therapy. Yes. Therapy. I'm going through schooling to be a Life coach and my chickens will be a part of my program. My question: are harnesses worth it? Pros, cons? I'm looking into it, as I will have a select few birds whom will accompany me out to retirement homes. Schools. Etc. Thanks y'all!
