Hello, I have been keeping chickens for about 9 years. But am always learning, so I ask this question of you more experienced keepers of the chicken. I have 14 8 week old Barred Rocks that I have been keeping inside my brooder and now my older chicken house. Before I moved them out to the chicken house I completely cleaned the inside, removing the litter and washing with bleach. I have raked all of the outside debris in the run that I can. Also, the old chickens that once inhabited this area have been moved to the new chicken coop/run. So they have not been in that area for 3 to 4 weeks. I fill you in to all of the above to ask this question. It is going to be close to 70 this weekend and I would like to let the babies outsidee for the first time and am wondering if it is safe for them to roam around the old run. I am mainly worried about coccidia still alive in the ground. I have not witnessed any of my older girls with any signs of this or other diseases. But I am worried about them being able to contract something since they have not been vaccinated or fed medicated feed. Am I being over protective or should it be all right. Thanks in advance for all replies/input.
