I went out to check on my chicks this afternoon and every sing,e one of them has the exact same fresh bleeder where the comb meets the beak. I have raised these 7-10 seekers all together without any problems. They are out in the coop with a small enclosed run accessible during the day. I put them out 2 weeks ago with a lamp in the coop since we have been having such warm weather. At first I thought it was the top bird pecking all the others, but they all have the exact same injury. I can find not place in the coop or run with blood where they all might have sustained an injury. Behaviorally hey are alert and not acting strangely with one exception. They have been hanging out in the coop for the majority of the day despite pleasant 68 degree weather. Normally, they would all be out in the run durning the day. They are grouping together in the nesting boxes quite a lot. See pic of injury. Note there is one on every single pullet.
