Just went in to make sure my chicks still had food and water and I found that one of my white rocks had died. It happens, but I didn't notice any problems last night or this morning and I don't see anything wrong with the body at all. I've only changed two things, I expanded the brooder so that they now have 1.5 sqft per chick and I sprinkled in some chick grit for them to scratch for. I'm thinking it may have eaten too much grit? If not what else would make a healthy looking chick just drop dead?
