Hi, I did read the other posts, but they were old and i needed some more specific information. One of my chicken has started to wheeze. She is also pulling her neck forward looking like she is going to throw up. I am concerned that it it Gapeworm or Choke. If I am going to give antibiotics - like Panacur - is it orally or in the food or water. How do you treat the ground? Is there a natural method that will save my hen - if Gapewrms are int he ground, will I not be able to have free range organic hens for at least 3 years? Please help with baby step instructions.
