my flock use to be very beautiful, but i noticed last year that they were starting to look very disheveled, losing feathers,burnt skin, and even the feathers they do have arn't full and pretty but they are sparse and rough. they just look ruff. i have a very large roo and i lost some hens last year and my roo being as "active" as he was with my girls started cutting up the remaining 4 of them. i put chicken saddles on the worse ones and there feathers still arn'tcoming in and its been a good 3 months with them on. its also not helping the feathers on their wings. so last winter they molted and i thought o great now there feathers will come in nice, and they did for about a month and them they started degrading again. and now my roo has a bare butt and he use to have beautiful long tail feathers. I'v never seen them picking at each other. what is going on? and what do i do about it?? i need help, i'm sick of having ugly chickens.
