So what with the chicken? Well, my father is a retired Chiropractor. For 40 years he fixed people aches and pains. Throughout that time he also had a small but dedicated list of dogs that he adjusted. Purebreds (eg labs) often have hip problems due to inbreeding.
The basic principle of Chiropractic is that most pain is causes from a bone or spinal disc shifting and pinching a nerve. The idea is that a physical shift of these bones back in place will help relive the pain. Chiropractors work on backs a lot as pinched nerves in your back can manifest pain in your hand. That’s the 30 second pamphlet on Chiropractic; you can read more at Wikipedia.
Back to the story. From a Chiropractic perspective, dogs (and most animals) are no different then humans and my dad has enjoyed adjusting different animals including dogs, goats, and sheep.
Last week he got a call from a lady who raises goats. My dad has been helping out keeping her goats healthy and happy. She said that he had a hen that got injured and was no longer laying any eggs. Could she bring it into town and get my dad to look at it? My dad said that he hadn't adjusted a bird since the 60's and didn’t think it was still alive. She said that was OK since he had to come into town anyways to meet with he lawyer then take her new Smartcar to the dealership as the stereo was giving problems.
They show up at the door and take the chicken out of the box. It looks half dead. He checks out her lower back along the spine and finds the problem along with a problem in the chickens neck.
The hen goes back in the box and the lady gives the bird 24 hours to get better or she is going to have chicken for dinner. The box goes in the trunk of the car and she is off to the lawyer. During the 45 min she is in there the chicken starts to feel better and next thing the bird has busted out of the box and is now flying around in the little smartcar leaving a huge pile of feathers and poo everywhere. Remember the car is less then a month old.
Three hours later the car smelled somewhat better and music was coming out of the speakers again.
And the hen? She is better then ever running around squawking and doing what they do best; lay eggs.
