Our birds are all over 20 weeks in age, and on occasion I have noticed what looks like a bit of blood in their droppings in the morning. The first time I saw it was after one of them laid a large double-yolker, so I assumed it was related. Yesterday I noticed a couple of spots that had small amounts of blood, but they looked like the shed intestinal lining pics from the poo page, so I did not think too much of it. This morning, I went out and again saw a couple of spots, but was quite shocked to see an actual puddle of blood on the dropping board. The board is covered in linoleum tiles, and considering the spreading of liquid on linoleum, I would estimate that it was about 1 Tbs. of blood. This clearly is not intestinal lining. The problem is that none of my girls are acting strangely. One of them was standing in the doorway of the coop with her eyes closed, but I've seen them do that before. Rather than sit here all weekend and monitor the situation, I would like to be proactive because we are not home during weekdays to react to problems. Advice? Treat for cocci and continue observation? Thanks in advance. Edit: I did check the vents of the one bird that was standing in the doorway as well as the others I could catch, and nothing looked out of the ordinary.
