I have a flock of 15 chickens. They are 9 months old, eat like pigs, run around and act fine. However, when I pick them up they feel skinny. I think they may be doing a little molting because they look a little rugged, not horrible, but not like they looked in the Summer. Anything I can do to fatten them up? We give them a handful of scratch every night before bed and we are able to watch them in the coop on the TV and they sleep fine. Any ideas why they seem skinny? I also let them free range a little every day and give them some sort of greens every weekend. Am I worried for nothing? Also, poop is good and normal. I have never wormed them because I asked about that a couple of weeks ago and no one thought they needed worming since they were so active and eating. Thanks for any help you can give.
