We processed 20 red rangers today. The first one we caught was a roo. We noticed that it had what looked like a scab at the breastbone. When it was plucked, we discovered that the area seemed to have pooled blood bulge. I cut into it and it had bloody like fluid and tissue like I've never seen on any of our previous meaties clutches (mostly cx). As the day progressed, many, if not all, the boys has a similar fluid filled sack at their breastbone of various sizes. I started the day thinking it was infection from ingrown feathers or infected feathers. But surely that's too much of a coincidence that almost all the boys would have this and none of the pullets. I've googled rooster anatomy to see if this is part of his business but can't really find anything. These were the oldest birds we've ever processed so I could just be ignorant about a more mature bird's anatomy. I should've taken a pic but I didn't. This normal or concerning?
