Well I can speak! I AM a mom with Cf and chickens :) How many of us are there, like 3? lol
I was diagnosed at 1 yr old, I am in my mid 30s and I have 3 children. We live on a horse farm though I don't tend to the horses much because the barn dust irritates me. We do hay, gardening, pets and just about everything else a horse/chicken property does and I'm very hands on.
I was raised on a farm. My mother was extremely vigilant with my Cf care and I was on a strict regimen. However she never kept me from doing normal childhood stuff (unless of course I was extremely ill obviously). I had to do chores just like my brothers, year round. Cf was never an excuse. I believe this is what helped shape me to be the hardworking Cf mama I am today.
I do a round of IV treatment on average every 2 yrs. I'm assuming you know Cf so that can describe my level of disease to you. I am very compliant with my health care but I also desire to live a life to the best of my ability.
My doctor knows I have chickens and animals. She has no problem with it. But then again, she also knows that I am extremely compliant with my treatments, so she has a level of trust in me. I am very good about handwashing, and my kids and regular visitors are trained to do so also.
One thing that was important to me was where I get my chickens from, and the concern over avian flu and other poultry disease. Obviously I get all my vaccines, having Cf...but I did chose to only buy birds from small local farmers that I know do not have a lot of traffic to and from large growers. I also decided to stay away from 4H shows this year, to be abundantly cautious.
Right now, I'm on IVs at home, for a little tune up. I am always sure to wrap my arm very well and stay totally covered when handling the birds. And obviously good handwashing. To me, this is no different than handling my dog or cat. I keep my coop very clean and above all, well ventilated! I want to be able to clean my coop myself so besides for the chickens, it has to be well ventilated for me too. Something worth noting is that some chicken keepers use diatomaceous earth. I use it too. However even food grade DE is not good to breathe in, so I have my husband mix that up whenever I use it, or if I he can't I wear a thick contractor's mask.
The enjoyment I get from my mini farm far outweighs anything else, for me. I get so much satisfaction from it, healthy exercise which is CRUCIAL for people with Cf, and me and my family are eating healthier than the average american for sure. I understand your concern as a loved one to a Cfer, and I thank you for being such a caring loved one! Just remember it isn't all what's on paper that matters. We live in an age where anything can be googled, and our minds can run wild with fear. For me, I have to live my life as best I can, doing what I love. I believe that happiness equals health to a degree. If I had listened to my fears year ago I wouldn't have been able to build the family I have today.
