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.
In women, the urinary tube serves only as a passage for urine from bladder to the region near clitoris and vagina, while in men; it is involved in dual functions that are the transfer of urine out of the body through penile opening as well as the ejaculation of seminal fluid.
