I found a mysterious poo this morning on the poop boards under the roost...it is normal size and shape, with white crest, but it also has a good amount of blood on it. Since it was on the poop board, I have no idea of knowing WHO it is. All of the girls are eating, drinking, walking around and sunbathing as normal. There appears to be nothing wrong, and everyone is acting normal. They look great. Other info: They're from McMurray, and vaccinated for Marek's and Cocci. They are just starting to lay, and out of 12, I have 9 laying. Some of their first eggs were this week. One of the eggs had a little blood smear on it, but that was it. Could the bloody stool be related to the blood on the egg? Is this normal?? If something's wrong, I want to address it ASAP! HELP!
