I have gotten cubalaya chickens the past two years. The first year i showed them and the hens became sick and died.The rooster also became sick but recovered. I figured they had picked something up at the fair. We bought three more last year, and one of the hens suddenly became paralyzed, lost a ton a weight, and is coughing up blood.(same thing that happened with the past two hens) This breed of chicken is rare so is it a possibility it is something genetic and there is nothing i can do? I have searched many diseases but nothing fits. She has been suffering for a month now, but i don't know how to put her down if it is fatal. has anyone else experienced anything like this or have any idea what it could be??
