So it took a week to figure this out. A bird died for no good reason last week. Then, I noticed one of my girls acting lethargic. Great. I'm thinking upper respiratory. I walk in the coop yesterday to a bloody murder scene. Two totally different birds are pooping blood. I already ran to tractor supply for all the stuff. Let's see what happens...fingers crossed. They are also dining on yogurt. I heard that helps. Just sharing.
