Anybody know what this is? I have an Easter egger hen that's at least 3 years old. She lays nearly every day. The last 2 days her eggs have been bloody (on the outside only). I checked her vent. It doesn't look Injured anywhere, but it's not the same as my other hens' vents. I'm not exactly an expert on what I should be looking for, however. She's been acting totally normal, it's just that her eggs have been bloody. Let me know what you think.
