this is my first time raising chickens. I have 14 Rhode island red chicks, about a week old. I can out to check on them and found blood in a pile of poop. it scared me. I called our local feed store and they recommended giving them amprolium in their water. and I was also told I should have been feeding them medicated feed. which where I bought them, they never told me that. so they are now on the medicated food, and have the amprolium in their water. am I doing this right? please help,I don't want to lose any babies. thank you!!!
