I have an 8 week old chicken that has feathers every where. The other two it is raised with are fine. Its feathers are all over the yard and the coop. Eats well, friendly as usual and like I said I never see them fighting and the pecking order is already set. Do I need to be alarmed? Is there anything I should for on the bird? Looks healthy and no change in temperment or anything else etc... Could it be diet? On grower feed for 3 weeks now but much heavier than the other two birds...total pig when it comes to treats. It acts like it hasnt eaten for days
