Ok. So I go out this morning to feed my chickens, and b/c of the rain last night I had to take the top part of the feeder off. Well, when I went to put it back on I noticed blood on it. Once I really started looking the whole thing was splattered in blood. It was still moist indicating that it probably happened this morning before I let them out of their coop. Immediately I start counting, and all are accounted for and acting normal. I start to look to see if there was evidence of an intruder. There was zero evidence. My 2 white hens have blood that's been splattered all over them. Any ideas as to what happened. They're all acting normal as of right now.
