The past two days I have found blood on the feeder. Quite a bit too. It's just a hanging plastic one from TSC. I thought maybe they were getting cut from the hook that hangs the feeder but I don't see any blood on it. I can't see any injuries on the chickens at all, just a few spots of blood on their feet. It looks like the blood is being smeared from their combs onto the lower area of the feeder just above where the food comes out. I don't have any clue whats going on but it's starting to worry me. Any of you had this happen before? BTW I'm still new to chickens. I have 5 hens that are all about 35 weeks old.
