Hi came home today from work and noticed a small clump of feathers in the coop, upon closer examination I found a few spots of blood here and there. I checked all the chickens over and found no obvious injuries. Everyone seemed to be getting along alright aside from the normal squabbles over treats and attention. I let them out to graze and everyone seemed content. Anything I should be watching for or am I dealing with normal growing pains? There are 6 mixed hens and one rooster all nine weeks old. Any advise is appreciated.
