I have had some chickens that have been sick and I have been using part of my back yard sectioned off as a recovery area for them. The only problem is, I have a few other pets that frequent the area. If i used a bleach solution and sprayed my yard with like a 1/10 ratio do you think that it would be enough to get rid of any viruses and bacteria that chickens carry? Or should I spend the extra money and buy a better disinfectant? I am also a bit worried about my grass, I don't want to kill it. I have another area inside the chicken yard that has no grass that I am going to spray with a much stronger bleach solution before I use the area again for my new batch of chicks. Its where I put the new chickens to introduce them to the flock for a few weeks before I integrate them. I just want to know if the bleach can kill everything that could possibly be out there. I am still battling an illness that has spread through my flock, and most everyone is over it, but I would like to clean my holding pen before I put anyone else in it. I will be needing it in a few weeks. If I put a pretty strong bleach solution on the ground, how long do you think it would be before its safe to put older chicks out there?
