When I went inside the coop today there was a lot of bright red dried blood all over (not in the stools, just by itself). I have two 21 month old hens. Even though both were acting normal and didn't have blood on them, I think I know which one it is because of the location on the perch. There was a dried puddle the size of a softball on the 2x4 perch w/ a few splash marks in the PDZ. Also there were 2 more dried puddles the size of baseballs in other locations on the perch, along w/ blood trails all over the coop from feet marks. In the coop also was an egg laid by the hen in question for the 1st time in 3 months, though no blood on it (they had been molting). I don't know what that means but I can't imagine that it's a coincidence that on the same day as the blood there is also an egg for the 1st time in 3 months. The only other thing that I did differently was on Sunday and Monday I gave them the greens off the top of organic carrots from the store. This incident either happened today or yesterday since yesterday I did not go inside the coop just the run. What does this mean and what do I need to do???
