Hi we started off with 2 dozen chickens 2 yrs ago, we are now down to 1 rooster and 15 hens. I have rhode island reds, new hampshire reds, and whatever whitish color breed from tractor supply. They constantly are picking or bullying each other to the point of making them bleed.. we have a pretty good sized coop and run, it is off the side of our shed, during the winter we let them out and they stay within the roofed part of shed which is dirt floor, so they can dust or just pick. I keep a heat lamp going when it's frigid, they get more than enough food and water and snacks. So why are they picking at each other so badly and what can i do to stop it. ??? It drives me crazy when i see them like this, I have a no more rooster or bullying salve that i use with tea tree oil, but sometimes i think that's worse cause they will go after that after i put on the hen that has it on.. HELP ME !!!!
