Im not new to owning chickens, as I’ve had them for several years and been through the ups and downs. Recently I got a new batch of 8 chicks from tractor supply, and when I moved them into the coop I would go out there and find one dead every other day or so. They showed no symptoms of sickness, just dropped dead. They were very skinny though, and soon after my adult chickens started getting sick and I lost some of them. Now my last rooster is sick and I’m suspecting worms. Every time I notice a chicken looking sick, they have lost a ton of weight in the shortest amount of time. This rooster was a big guy and he is so skinny now but I know he is eating. I watch him and I hand feed him. I have separated him from the flock and am giving him probiotics and electrolytes, but seeing no improvement. This is the third time I’ve taken him out in a month. He will be sick and then fine after a few days. His poop is the color of green grass and the fact that he isn’t improving is concerning me. Please help. I’ve lost more than half the flock to whatever this is. I’ve cleaned and bleached the coop and cleaned and bleached the waterer and feeder since I have taken him out. Does this sound like worms? If so what kind? And what kind of dewormer should I use? Any help is greatly appreciated.
