I've been following this blog for a few weeks. I have chicks I purchased at rural king last weekend. I was told they were 2 weeks old. I bought 10 and lost 2. Why did they die and not any other ones? Also , why do some of them have poop stuck to their backside? Also , I have not seen people post about the kind of chicks I bought? is their a preference among chicken owners based on egg production?
