Hi All, Background... I have 17 BO's that are about 3 years old. They get fresh water and food daily, plus treats. They free range in my backyard eating fresh goodies I use deep litter method in a coop with a wooden floor, I do a complete cleaning once a year. I worm them yearly and dust them. All in all I say I take very good care of my girls to the point of spoiling them. I post this thread because I came in contact with someone who said that owning chickens can make you sick if not kill you. He sited all the diseases that they can carry and the chores of cleaning the coop and pen can be hazardous to you health. He does have a condition that he said his dr calls chicken coop disease which results in a bad cough and lung problems. He did at one point work at a chicken farm which he says the illness came from. Now I am concerned and a bit confused on what position I should take in dealing with my girls. In a nut shell, I am a little bit scared. Those who have kept chicness for a long time or been around them for most of their lives, is this something that I should worry about. Should I fear for my health because I own backyard chickens. Thanks Here is a pic of my set up, if it is helpful.
