My hens have been looking homely and ratty for some time now, I had roosters to blame I thought, so I got rid of all but 1 small sea bright bantam rooster. Still after many months of the other roosters being gone I notice my hens have missing feathers on their back and top of wings, one is especially ratty and has hardly any tail feathers. They are not nice and fluffy and plump, just sort of scrawny and rough looking. Could this still be from my 1 small rooster? I don't notice the hens picking on each other much when i go out and watch them but on occasion there are spats. My coop is kept clean and they have a nice big run to be out in.....I have had a few randomly get sick and die and I keep coming back to worms but I am really not thrilled about tossing eggs ....I have also heard that the hens that are laying a lot tend to look rough and when they are shiny and big that can mean they aren't laying much any more but I have no clue if that has any truth to it. Any advice would be much appreciated, I want healthy looking hens!
