Howdy! My wife and I have successfully raised chicks before, but this time, not so. We are starting our 5th day after receiving 25, and now we are down to 15. I read the other posts but never saw anything on dirt or gravel. Could it be that our brooders are too clean? I'm guessing that the chicks digestive systems are becoming bound, so I added something to help with grinding the food. I'll keep you posted, but anybody else want to weigh in on this?
