Slips
Many times, particularly with beginners, while the operation seems to be entirely satisfactory, the bird will turn out to be what is known as a “slip.” A “slip” is neither cockerel nor capon, but is between the two, possessing the mischievous disposition and the appearance of an ordinary cockerel, but, as a rule, being unable to reproduce. This condition is due to the fact that a small piece of the testicle is left in the body. This piece often grows to a considerable size. As the “slips” possess the same restless disposition as the cockerels, they grow and fatten little if any better, while they do not bring as good a price in the market as the capons. Consequently it is well to use every precaution in order to avoid “slips,” as they are unprofitable as compared with capons. With the greatest care, however, “slips” are more common than are deaths due to the operation. The percentage varies all the way from 50 per cent with beginners down to 2 or 3 per cent with experts.
