I'm not sure if this is an emergency but from everything I've read on here chickens go fast so I just want to make sure I'm not missing something important. I introduced 4 new pullets and rehomed 3 cockerels this past week so now I have a total of 7 pullets, ages range from 7-11 weeks. The pecking order has been shaken up of course but things are cooling down. One of them seems a bit depressed, pulling out a few feathers and hanging out in the henhouse by itself. She is the 11 week-old. Today when I went out the coop there were drops of blood in the henhouse under the roost and tracked over the roosting pole and some of the shavings on the floor. I checked all the birds all over and can't find a thing! This is the second time I've seen this. I'm totally confused. I don't think it's from them pecking because then I would see it on their bodies, right? So I'm thinking coming out with their poop? But its not bloody stools either. It is like drops of blood. Otherwise all the birds are eating, drinking and active. What should I do? or what should I be looking for? Thank you so much for any help you can offer.
