Commercial poultry farms have equipment to take off the feathers, but you will have to do it buy hand. Finally, you need to market your chickens. Supermarkets have contracts with major suppliers, so you cannot sell them there. You can try selling them at a flea market, but you would need a booth.
Antidiuretic hormone (ADH): A relatively small (peptide) molecule that is released by the pituitary gland at the base of the brain after being made nearby (in the hypothalamus). ADH has an antidiuretic action that prevents the production of dilute urine (and so is antidiuretic).
Antidiuretic hormone (ADH) is produced by an area of the brain called the hypothalamus. ADH controls how your body releases and conserves water. Antidiuretic hormone (ADH) is produced by an area of the brain called the hypothalamus. This hormone is stored in and released by the pituitary gland. ADH controls how your body releases and conserves water. When ADH (also called vasopressin) is produced in excess, the condition is called syndrome of inappropriate antidiuretic hormone (SIADH). This overproduction can occur in places other than the hypothalamus.
