Yesterday, I looked into the brooder and there was blood smeared here and there, I checked all 4 chicks over for wounds but came up with nothing. It has to be the in the poop then
They have been on medicated starter since I got them and they are almost 7 weeks old and haven't been moved outside yet. What could it be? They are acting perfectly fine and aren't droopy or anything, they are eating and drinking normally. I can't tell if only one is pooping blood or they all are, but not every poop is bloody.
What can I do
