What are caponizing “slips?
Slips are males in which some testicular tissue was left during the caponizing operation. Even a minute amount of testicular material has the ability to secrete sufficient male sex hormone to give the bird the general characteristics of an intact male. The length of time before slip characteristics develop will depend on the amount of testicular tissue left in the bird. Slips are intermediate between capons and cockerels in their ability to put on fat and their carcass quality. They should be disposed of as soon as they appear in the flock.
