Thank you SO MUCH! I've scraped the top layer of the pen and extension. I always keep their inner coop very clean. Their sandbox is normally changed weekly. I wet it down, mix it with a shovel, and train a fan on it to help with the heat. Ice bottles, ice cubes, in water containers, and water melon at the peek of the temperatures. I've ordered some disinfectant suggested here, for cleaning the coop. I change the straw in the stalls every day. I'm going to start with the iodine tomorrow.
Question: How do I apply the iodine? by a soaked q-tip? cotton ball? Will it burn her? If I had put fine screen around the chicken wire, would it have prevented this? I'm so grateful for any information you can give me. These are like my babies. Yes, they give me eggs. OK. I have them, but haven't eaten them...yet...I will...later.
