I have 8 hens and 1 rooster (2 Brown Leghorn, 2 Silver Wyandotte, 2 Rhode Island Red, 2 Araucana and 1 Araucana rooster). One of my Araucana hens has always been "picked" on but lately bot Araucana and Silver Wyandottes have a nice bare plucked patch on their back at the base of their tail. I spent some time today watching. The rooster is the main culprit. He just picks someone out and hammers them. One of the Brown Leghorns is doing the same thing, but maybe not quite as bad. We raised all the chicks from day old. They have just started laying and now they are plucking each other. They get "LayMaker" for feed and we scatter cracked corn everyday. Started throwing them table scraps and sunflower seed today and picked up some Avia Charge for the water. They have 32 square feet inside with 2 elevated 4' nesting boxes. The outside area may be a bit small, they have 50 square feet outside but can move in and out at will. We are going to "Vicks" the bare chickens tonight in an attempt to give them some relief and deter this behavior. What is my rooster doing? Is he just mean? I split him off from the hens for awhile so I could observe the hens by themselves. Boy was he TICKED!! Any advice would be appreciated.
