I ordered some chicks from McMurray about 3 weeks ago. This morning i woke up and had 3 dead chicks. I also noticed some blood drops on the shaving in the brooder. I checked all the chicks to make sure no one was bleeding from a peck or something and i didnt see anything. I cleaned out the entire brooder and put some new shavings down and i already see more blood spots. I am thinking that it is bloody poop. I also noticed some of the chicks not being able to open one eye. It is weird. I will pick up a chick and the eye will be closed then i will put it back down and check on it again later and both eyes will be open. From reading about Cocci, i think i am supposed to be feeding them medicated feed because this prevents Cocci correct? I am not sure if the feed i am giving them is medicated or not. I will look in the morning. Here are some details so some of yall can help me pick out what is wrong with them I had 31 chicks and i have lost 5 chicks in all since i got them. I am keeping them in a brooder with access to fresh food and water. Noticed the bloody poop but other than that the chicks seem to be in good shape except for a couple of the chicks not being able to open an eye. After a while, the eye opens back up... Some breeds i have are red stars, buff orpingtons, leghorns, ee's, BCM's, delawares, turkens, light brahmas. Some of the chicks are half size of the others. Seems they are growing at different rates. The chicks are about 3.5 weeks old. Please help me figure out what is wrong with them. If it is Cocci, please help me figure out how to heal them. Some good links would also be great.
