I have chicks that are about 9 weeks old. I am finding droppings that look like blood. It looks like the whole dropping is blood, not like a dropping tinted with it. So it looks as though someone is literally pooping blood. I have 20 or so chicks together so I dont know which one is doing it. I am not finding lots of these droppings looks more like maybe one bird. Out of these birds there are 5 that I bought at tractor supply and the rest are eggs I bought locally from a reputable lady, and hatched myself. A few days ago I found one of the bantams I bought at tractor supply dead, with no signs of anything, this a.m I found another one of the bantams from tractor supply dead, and bloody droppings in the pen. but no signs of blood on the chick. In case it matters any: The chicks were raised in the house with newspaper for bedding until they feathered out, they are currently in a pen in the barn with sawdust/hay for bedding. They have not been outdoors yet. I am new to raising my own chicks and this is the 1st time I have had to deal with blood stools, I am not sure what to do?
