I noticed today that 6-8(24 total) of our ladies have dry blood around the top and bottom of their vent area(some the top around butt area and some around the bottom of vent area). I was dusting them for lice and that is when i noticed it and it looked kinda like peck/bite marks. I dusted them 2.5 to 3 wks ago and never saw any blood on any of them!!! They must have had a squabble the prior time as there was dry blood in the coop but none on any of the birds. Do you think that this is what happened again, but this time it was a serous brawl? Could it have been from a predator(but none are dead and doesn't appear to be any other wound marks elsewhere on their body) ?They seem to be eating and drinking as normal and the blood was definitely dry and old/crusty but i wonder what could have happened? The eggs are collected every 1-2days as is their water and there doesn't seem to be any blood in the coop this time, so...????
