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.
When the catheter is in the bladder, a small balloon is inflated to keep the catheter in place. The urine drains from the bladder into a bag that is usually attached to the thigh. Sometimes the catheter tube has a valve that lets you drain the urine into the toilet or other container. You may need this type of catheter if you have nerve damage or if you have problems with your bladder or urethra.
