The chicks and the chickens should be close to the same size and it also depends on how many are in your existing flock.
1 Most often, the catheter is inserted through the urethra. This is the tube that carries urine from the bladder to the outside of the body.  Sometimes, the provider will insert a catheter into your bladder through a small hole in your belly. This is done at a hospital or provider's office.
Urination is the release of urine from the urinary bladder through the urethra to the outside of the body. It is the urinary system's form of excretion. It is also known medically as micturition, voiding, uresis, or, rarely, emiction, and known colloquially by various names including tinkling, peeing, weeing, whizzing, and pissing. In healthy humans (and many other animals) the process of urination is under voluntary control. In infants, some elderly individuals, and those with neurological injury, urination may occur as a reflex. It is normal for adult humans to urinate up to seven times during the day.
