I have been using sand in my coop for over a year and a half now with great success. I replaced the sand about 3 months ago with a mixture of half sand and half decomposed granite. Since then, I've been having trouble with my chickens' eyes. They have been getting crusty and infected. One hen has been dealing with some type of infection that I can't seem to get rid of. I've treated them all for an URI, but I'm still having the issue. Could it be because of the decomposed granite? I was told that the decomposed granite would be a good source of grit, but maybe I was told wrong? I'm thinking about replacing it with just sand. What's your thoughts? I'm beside myself and just want my girls to feel better.
