Blood

[Jess72180]

I just went to the coop to check on our 7 1-2 week old chicks and I saw one had a trail of thick looking red blood coming from her butt. I watched her poop and it came out normally without a streak of blood in it but she did pull it out with her beak a little. Does anyone know what it could possibly be? We had to leave and won't be back until tomorrow. I am worried we may come home to a dead chick.

If you can post a photo of it that would be great.
From your description it sounds like intestinal shedding.
