Welcome to chicken parenthood! Its going to be a fun journey. Your therapist has the right idea, I was diagnosed with PTSD when I was 5 years old when my father was killed in action in afghanistan. I am now 17 and our PTSD's are very very different I'm sure, but I find raising chickens help distract and calm me. I used to not be able to go outside by myself because I was so terrified but now I go outside all the time to see my chickens! I hope your chickens help you too and we are all so thankful for your service!
