When I checked on my pullets this morning (they're about 3 months old), I noticed several bloody spots in the house. It looked to be something that had possibly been pooped out but I'm not sure. I checked every bird and found no sign of any injury. I checked their rear ends, too, but they were all clean. I checked on them after work and there was a few more blood spots. Not terrible amounts of blood, but enough to make a mama worry. Anyone know what is happening or had this happen before?
