I put my chickens in the coop almost a month ago and within the past few weeks I've noticed that there are always feathers all over the place. Is this normal? I've seen a couple feathers on the birds that seem like they're sticking out or ready to fall off. How do you know if the flock is in molt? What will it look like? I've never seen any of the birds picking at each others feathers. Could it be mites? I've used diatomaceous earth quite liberally but I've never seen a chicken taking a dust bath in the available area. What could be the problem?
